The roles of the consistent Jacobian matrix and the material tangent moduli, which are used
in nonlinear incremental finite deformation mechanics problems solved using the finite …

The crack band model of Bazant and Oh (1983), referred to as the CBBO, is frequently used
in material damage and softening analysis. Care should be taken in the implementation of …

This paper presents an analysis of the constitutive relations of Hooke-like isotropic
hypoelastic material models in Lagrangian and Eulerian forms generated using corotational …

The objective stress rates used in most commercial finite element programs are the
Jaumann rate of Kirchhoff stress, Jaumann rates of Cauchy stress, or Green–Naghdi rate …

The paper briefly summarizes the theoretical derivation of the objective stress rates that are
work-conjugate to various finite strain tensors, and then briefly reviews several practical …

Volume conservation during plastic deformation is the most important feature and should be
realized in elastoplastic theories. However, it is found in this paper that an elastoplastic …

ABET expects the documented learning outcomes, that are mentioned above, and that
support the program educational objectives, to apply to individual students. Assuming that …

An elastoplastic theory is not volume conserved if it improperly sets an arbitrary plastic strain
rate tensor to be deviatoric. This paper discusses how to rigorously realize volume …
