Physics-based crystal plasticity models rely on certain statistical assumptions about the collective behavior of dislocation populations on one slip system and their interactions with the dislocations on the other slip systems. One main advantage of

The capability of high-resolution modeling of crystals subjected to large plastic strain is essential in predicting many important phenomena occurring in polycrystalline materials, such as microstructure, deformation localization and in-grain texture

A severe obstacle for the routine use of crystal plasticity models is the effort associated with determining their constitutive parameters. Obtaining these parameters usually requires time-consuming micromechanical tests that allow probing of individ

In this paper, a four-layer road structure consisting of an edge transverse crack is simulated using three-dimensional finite element method in order to capture the influence of a single-axle wheel load on the crack propagation through the asphalt co

In this paper, the compact tension-shear (CTS) specimen is studied using three-dimensional finite element analysis. The values of T -stress are calculated for the complete range of mode mixities from pure mode I to pure mode II. The results show that

The critical mode I stress intensity factor obtained from fracture tests on laboratory specimens is often used as fracture toughness in brittle and quasi-brittle materials. However, considerable variations in the experimental results reported for a g

The shape and size of the plastic zone around the crack tip are analyzed under pure mode I, pure mode II and mixed mode (I+II) loading for small scale yielding and for both plane stress and plane strain conditions. A new analytical formulation is pre
