Повний текст джерелаIn this work, beneficial effects of tensile mean strain on fatigue behavior and microstructure of superelastic NiTi (i.e. Nitinol) are studied. Most applications, such as endovascular stents made with NiTi, are subjected to a combination of constant and cyclic loading; thus, understanding the fatigue behavior of NiTi undergoing mean strain loading is necessary. Cyclic strain-controlled fatigue tests are designed to investigate the effects of tensile mean strain on fatigue of superelastic NiTi. Experimental observations show that combinations of large tensile mean strains and small strain amplitudes improve the fatigue life of superelastic NiTi. This behavior arises from reversible, stress-induced phase transformations. The phase transformations cause “stress plateaus” or strain ranges with no change in stress value. Scanning electron microscopy (SEM) of the fracture surfaces of specimens revealed generally short crack growth. Electron backscatter diffraction (EBSD) found the amount of residual martensite to be about ~8%, regardless of loading conditions.

Повний текст джерелаThis thesis introduces an Equivalent Fatigue Load (EFL) approach for the multiaxial fatigue design of elastomeric parts. As direct Finite Element Analysis (FEA) calculations of automotive in-service loads (Road Load Data (RLD)) are too expensive, the objective is to derive simplified load blocks as a realistic input for numerical damage calculations. Three streps are applied for this method: the localization method, the material damage function and the EFL determination process. Various fatigue tests have been conducted (415 samples) to study the fatigue behavior of this complex type of relaxing and non-relaxing multiaxial loading on natural rubber specimens. Lifetime and crack features are analyzed to eventually introduce an appropriate critical planebased fatigue measure and to establish a novel mean strain effect model. This criterion is generalized throughout an original critical plane search method. To estimate the local mechanical response (localization method), this thesis identifies an axes-coupling method that is fitted for the nonlinear nature of elastomeric structures. It is based on the multiplicative decomposition of the deformation gradient tensors. These two steps are then implemented in the framework of the EFLdetermination process. For this, a global optimization method is added to determine the simplified load blocks, causing locally the same fatigue behavior in the given structure. The computational costs of this optimization are reduced by only considering a subset of the most damaged material points for EFLdetermination. Finally, the method has been challenged on a specimen to outline its capabilities and to validate the approach

This work is aimed to understand the mechanisms for evolution and reversed evolution of dislocation structure under variable strain amplitudes, using automotive-grade interstitial-free steels (IF steel) under strain ratio (R) = 0 condition. The microstructures were mainly examined by the SEM under BEI/ECCI mode and TEM were used for this study. Near the endurance limit, the dislocation cells smaller than 2μm develop preferably along grain boundaries and triple junctions among the grains. Within grain interiors, it is hardly observed these small dislocation cells and cyclic hardening even at εmax =0.2%. When strain amplitudes were controlled at a range from εmax = 0.25% to 0.6%, a secondary cyclic hardening occurs prior to fatigue failure and less than 2um dislocation cells rapidly developed thoroughly. The secondary hardening rates were found to be directly proportional to the strain amplitudes. For high-low strain fatigue tests, while the maximum strain was decreased from 1.2% to 0.2% or 0.15%, dislocation cells were collapsed first and re-grouped into loop-patch structures due to the gliding behavior of dislocations changing from multiple-slips to single-slip. However, once the strain range is further reduced to 0.1%, dislocation cells would persist, showing no signs of collapse. Moreover, the reversal development of dislocation structures is independent of strain ratio. Furthermore newly developed loop patches are usually confined within dislocation domains with very condensed dislocation cell walls with high boundary misorientation.

Applying on the actual engineering project, components are usually subjected to a non-symmetric cyclic stress/strain load. Therefore, this study will examine a main purpose which is mean stress/strain effects on cyclic behavior and fatigue life for 316 Stainless Steel. In this experiment, specimens were subjected to a monotonic tension test and three kinds of cyclic strain load tests, in which, cyclic strain load tests includes fully reversed fatigue test, mean strain 1%fatigue test, and strain ratio 0.5 fatigue test. The experimental result showed that no significant mean stress been found in fully reversed fatigue test. It's easier to produce mean stresses when material subjected to large mean strain and small strain amplitude at the same time, hence reduces the fatigue life. By the damage parameters SWT, and stable strain energy density in tension condition, to estimate the fatigue life, and add a text to judge whether experimental results fit in with Massing's hypothesis. If it does fit, the stable hysteresis loop can be estimated by the double cyclic stress-strain curve. Unfortunately, the result only by the strain ratio 0.5 fatigue test fits Massing's hypothesis. After getting the prediction of fatigue life, in order to confirm the ability of prediction, a value, was obtained by a simple statistical analysis. Finally, result shows that the damage parameter provides a best estimate of fatigue life in this study.

In this study, author would devote to the effect of the superimposed mean strain on fatigue life and cyclic stress-strain curves. Hence, a series of the strain-controlled cyclic loading experiments with several combinations of strain amplitudes and mean strains have been performed on closed-loop servohydraulic test machines for AISI 316 and 304 stainless steels. In the cyclic stress/strain behavior, a modified expression that describes/predicts the cyclic stress/strain curve under an applied mean strain is developed. Using the modified expression, the effects of superimposed mean strain on the cyclic stress-strain curve can be examined by comparing two descriptive parameters. Furthermore, both of the usual description and the modified expression are identical for cyclic stress-strain curve obtained from completely reversed fatigue test. The damage parameters corresponding to the Smith, Watson and Topper criterion can be extracted from the modified cyclic stress-strain curve (CSSC) expression to predict the fatigue life with mean stress/strain. In addition, based on the two given hypotheses in this study, a simply approach is derived for the determination of the stable mean stress that occurs in strain-controlled tests with an imposed mean strain. The evaluated stable mean stress is applied to fatigue life prediction based on the Morrow mean stress parameter. In theoretical analysis, the whole study of this paper is made in the framework of endochronic theory of plasticity with yield surface. Based on the hypothesis that the stable hysteresis loop exhibits symmetric behavior with respect to the coordinate , an analytical expression is proposed to describe the basic cyclic stress-strain curve obtained from completely reversed constant strain amplitude. And the same time, a set of algebraic equations is developed to express the stress-strain behavior for the tensile branch curve of stable hysteresis loop with a specific mean strain level. Furthermore, according to the symmetric hypothesis, the stable hysteresis loop with a specific mean strain level can be developed. Based on the experimental observation for the stable hysteresis loop with superimposed mean strain, from a viewpoint of the movement of stable hysteresis loop, author explains the effect s of the superimposed mean stress or strain on the fatigue and the cyclic stress-strain curves. And the phenomenon is found that only the plastic strain energy in the tensile part has the obvious effect on fatigue life. According to the observed phenomenon, author assumes that fatigue life is influenced by the magnitude of plastic strain energy in the tensile part. Under the explanation, a new fatigue damaged parameter that takes account of effects of superimposed mean stress/ strain on fatigue life is developed. In the low cyclic fatigue regime, the fatigue parameter based on the plastic strain energy in the tensile part can be applied to predict the fatigue life with superimposed mean stress/ strain. In this study, some important phenomenon concerned the effects of superimposed mean strain on the stable stress-strain behavior are observed and analyzed. And those proposed methods are examined in relation to the stable mean stress evaluation and the two proposed stress-strain correlations based on the endochronic theory of plasticity with yield surface. For AISI 316 and 304 stainless steels, the proposed hypotheses for stable hysteresis loop are acceptable by the experimental observation. Under the condition, the experimental results show the data generated by proposed formulation concerned the stable mean stress is in qualitative agreement with experimental data. Subsequently, a series of experiments for AISI 316/ 304 stainless steels and test data of 1070 Al Alloy have been performed to confirm the validity of the two developed stress-strain correlations. It has been shown that the developed correlations are capable of describing the experimental results of three different metals considered. Furthermore, in prediction of fatigue life with superimposed mean strain, a satisfactory result based on the damaged fatigue parameter of is shown. It is worthy noting that the curve can be directly obtained by modified the standard curve from fully reversed fatigue tests since the magnitude of is equal to a half of the magnitude of .
