When a solid metal is subjected to a load of small magnitude, it deforms elastically such that the strain is directly proportional to the stress and when relieved of the stress, it eventually returns to its original dimension. Elastic deformation is

A three-dimensional extended finite element method (X-FEM) coupled with a narrow band fast marching method (FMM) is developed and implemented in the Abaqus finite element package for curvilinear fatigue crack growth and life prediction analysis of m
Defining material coefficients of anisotropic yield function as scalar functions of equivalent plastic strain is usually employed to model subsequent anisotropic behavior of metallic sheet. However, it might be difficult to take into account the inf
The versatile Bouc–Wen model has been used extensively to describe hysteretic phenomena in various fields of engineering. Nevertheless, it is known that it exhibits displacement drift, force relaxation and nonclosure of hysteretic loops when subject
