Full textIn this work, a new bond model with nonlinear shear failure criterion is first proposed and implemented in PFC for describing mechanical behavior of isotropic cohesive granular materials such as sandstone. A large number of compression tests have been performed on 3D samples. The results show that the effect of confining pressure on compressive strength and failure pattern is well described by the proposed bond model. Effects of loading path and the intermediate principal stress on deformation and failure have been also investigated. After further extending parameters on elastic and strength, two bond models: the proposed bond model and the improved smooth joint model, are coupled to character the anisotropy of strength and deformation in anisotropic cohesive materials such as sedimentary rocks. A series of conventional triaxial compression tests with different loading paths have been performed and numerical results are in good agreement with experimental data, especially for elastic response and strength properties. The failure mode transformation between weakness layer and rock matrix under different confining pressures has been well described. Furthermore, the proposed bond model has been extended to study hydraulic fracturing process in cohesive materials. A representative hydraulic fracture propagation process has been presented. Influences of different factors, such as confining pressure, fluid viscosity and fluid injection rate, on hydraulic fracture extension have been investigated. Finally, we have developed a dimensional reconstruction method of block shape irregularity and studied its effects on block impacts using an energy based approach

Full textThis manuscript is a contribution to the study of the crack propagation in very high cycle fatigue domain. We develop a numerical tool which allows to model this crack propagation in mode I and to study the formation of fish eye crack, a characteristic of this failure. Firstly, an iterative numerical procedure based on three dimensional finite element method is developed to study the evolution of crack form during the crack propagation and to calculate the number of cycles to failure when it is not possible to find an analytical solution. The virtual crack closure technique is used to calculate the stress intensity factor in each step of crack growth process. Secondly, a coupled thermomecanical finite element model in 3D is proposed to estimate the evolution of the temperature field during the crack propagation. The problem is solved into 2 steps. In the first step, we calculate the plastic energy per cycle from the cyclic plastic zone at the crack front. In the second step, we use a fraction of this energy as a mobile heat source to estimate the temperature field evolution. The plastic energy per cycle is calculated by two methods. The first one is based on an elastic-plastic finite element analysis with a perfectly elastic-plastic constitutive law. The second one is based on an empirical relation between the energy plastic per cycle per unit of crack length and the range of stress intensity factor. Numerical results obtained agree fairly well with experimental results

Full textDebonding at the interface is one of the main failure modes for "inclusion-matrix" materials. From a modeling point of view, it is therefore essential to describe the behavior of such materials with partially debonding interfaces.In the framework of the linear elastic fracture mechanics (in plane elasticity), this work concerns first of all the analysis of interfacial fissures located at the boundary of a circular inclusion, immersed in an infinite matrix. The generic solution of such a problem, based on the complex potential method of Muskhelishvili, has been proposed by Perlman and Sih (1966). This general solution was applied successively to the cases of a single crack and two symmetric cracks by Toya (1974) and Prasad and Simha (2002, 2003), respectively. We use here the methodology of Perlman and Sih (1966) to calculate the solution to the problem of two interface cracks of different lengths, but sharing the same axis of symmetry. On the basis of the solution obtained, we then analyze the propagation of two initially symmetrical cracks. We show that the propagation can be asymmetrical: the length of one of the cracks grows, while that of the other remains constant.Then, the Mori-Tanaka homogenization scheme is adopted to study the effect of the partial debonding of the interface on the macroscopic behavior of the material. Finally, we present a macroscopic stress-strain curve of the "inclusion-matrix" material subjected to uniaxial traction taking into account damage due to debonding at the interface. The influence of parameters such as volume fraction of inclusions, particle size and initial crack angle on this curve is examined
