Size effect on elastic properties of random composites

G. Cailletaud, D. Jeulin, P. Rolland

In addition to the prediction of effective elastic properties of randommedia, the statistical variations of these properties for finite sizespecimens are of practical interest…

3D finite element analysis of rubber‐like materials at finite strains

C.H. Liu, G. Hofstetter, H.A. Mang

The paper starts with a review of constitutive equations forrubber‐like materials, formulated in the invariants of the rightCauchy—Green deformation tensor. A general framework…

Mesh optimization for problems with steep gradients

P. Coorevits, P. Ladevèze, J. ‐P. Pelle

In this paper we present a new method of mesh optimization whichautomatically accounts for steep gradients. With this method, the user needsno previous knowledge of the problem…

A simple finite rotation formulation for composite shell elements

W. Wagner, F. Gruttmann

In this paper we derive a simple finite element formulation forgeometrical nonlinear shell structures. The formulation bases on a directintroduction of the isoparametric finite…

Generalized eigenvalue formulation of the helmholtz equation by the trefftz method

N. Kamiya, S.T. Wu

A new‐type eigenvalue formulation of the two‐dimensionalHelmholtz equation is presented in this paper. A boundary integral equationis derived using the T‐complete functions…
