This paper discusses the homogenization method to determine the effective average elastic
constants of linear elasticity of general composite materials by considering their …

The physical basis of computationally tractable models of crystalline plasticity is reviewed. A
statistical mechanical model of dislocation motion through forest dislocations is formulated …

A Lagrangian finite element model of ductile penetration is developed. Adaptive meshing is
accorded a key role in following the large deformations which develop during penetration …

Mechanical engineering, an engineering discipline forged and shaped by the needs of the
industrial revolution, is once again asked to do its substantial share in the call for industrial …

An adaptive meshing method tailored to problems of strain localization is given. The
adaption strategy consists of equi-distributing the variation of the velocity field over the …

We present work aimed at develo** a general framework for mesh adaption in strongly
nonlinear, possibly dynamic, problems. We begin by showing that the solutions of the …

A numerical methodology which determines the quality (or robustness) of a posteriori error
estimators is described. The methodology accounts precisely for the factors which affect the …

In the product development process, structural optimization plays vital role because it deals
with size, shape and topology of the structures. However, structural performance greatly …

We develop a simple mesh-smoothing algorithm for adaptively improving finite-element
triangulations. The algorithm makes use of a posteriori error estimates which are now widely …

A review of adaptive grid generation is presented with an emphasis on the basic concepts
and the interrelationship between the various methods. The concepts are developed in a …
