Повний текст джерелаThe thesis proposes a multi-scale comprehensive analysis of low cycle fatigue of shape memory alloys (SMAs). First, low cycle fatigue of SMAs is experimentally investigated; comprehensive tensile-tensile fatigue tests under both stress and strain controlled loadings at different frequencies are carried out and results are discussed. Second, a new strain energy-based fatigue criterion is developed; it is shown that the use of total strain energy is a relevant parameter to predict fatigue lifetime of SMAs for different thermomechanical conditions and under different types (strain-control or stress-control) loadings. A physical interpretation of the mechanism related to the low-cycle fatigue of SMAs is then provided based on the conversion of hysteresis work into dissipation and stored energy. Third, fatigue crack initiation during cyclic stress-induced phase transformation is modeled based on transformation induced plasticity (TRIP); it is shown that the maximum temperature during the cyclic loading is a relevant indicator of the fatigue of SMA. Furthermore, the effect of the macroscopic mechanical load on the the fatigue lifetime is addressed as well as the spatial location of crack initiation. Finally, a mechanical training process that allows enhancing resistance to low cycle fatigue of SMAs is proposed

Повний текст джерелаInconel 718 is a nickel-based superalloy widely used by aeroengines manufacturers like Safran Aircraft Engine to manufacture turbine disks. After forging, disks are given an ageing treatment called “Direct Aged”. In service, during cruise, these critical components handle hold-time periods at constant loading. It is well known, although not fully understood, that hold-time increases crack growth rates (CGR) in Inconel 718 as well as others superalloys. Therefore, this study focuses on crack propagation under hold-time conditions in DA Inconel 718, at 550°C and 650°C. Experiments were carried out for different hold-times, up to 1h. Developments on the crack monitoring technique (DCPD) led to the conclusion that the most damaging part of the cycle is load-reversal (fatigue contribution). This contribution is enhanced by the hold-time period. Holdtime leads to dramatically curved and tortuous crack front, contrary to pure fatigue cycles. A numerical framework was developed, combining crack growth and DCPD simulations, so that “numerical tests” can be carried out. Using this method, crack growth simulations were performed from curved and tortuous, experimentally reproduced, crack front. It was concluded that increased crack CGR under hold-time conditions are closely related to the crack front morphology and its evolution during propagation. More complex tests, with overloads or under vacuum, were carried out. When the hold-time effect is inhibited, complex morphologies vanish. Such morphologies were associated to local inhibition of the environmental damaging effect due to local high plastic strain and strain rates. The large variety of experiments, presented in this study, was then successfully analyzed considering the effect of local strain rates which greatly influence the crack growth behavior of Inconel 718

Fatigue is the main reason that causing heavy casualties in steel structures. In many cases of steel structure which have been fatigue failure, most of the fatigue crack initiate at the toe of weld. Because the irregular geometry of weld toe, small cracks will start from weld toe after the force loading of the members. The rate of crack growth will be faster after various cracks combined, also the crack shape will change drastically. This study use finite element method with the previous theory and establish a set of automated computer program to simulate the foregoing growth process. The result showed that whether the initial crack shape is semicircular or very shallow, the value of aspect ratio is between 0.6 and 0.8 in the last stage of growth. And the maximum length of crack growth, , model width, b and height, h, are insignificant on crack shape growth simulation. This study also discuss the crack shape evolution of two symmetrical coplanar semi-elliptical after crack combined. The simulation results show that the greater distance between the center of the semi-elliptical and plane of symmetry, the required distance of the leading edge of two cracks grows into a single smooth curve is also larger.

Повний текст джерелаThis work concerns the topical scientific and technical problem of increasing the residual lifetime of elements of aircraft structures with stress concentrators. High requirements for the reliability of structures and their safe operation are of particular importance in conditions of cyclic loading and high stresses. An important scientific task is to assess the residual lifetime of structural elements with operational damage (fatigue cracks) in the vicinity of functional and mounting holes with high requirements for safe operation
