Discretization influence in strain—softening problems

L.J. Sluys, M. Cauvern, R. De Borst

The dispersive behaviour of waves in softening problems is analysed.Attention is focused on the influence of the numerical scheme on thedispersion characteristics in the process…

Fully stressed topological design of structures using an evolutionary procedure

E. Hinton, J. Sienz

An automated fully stressed design approach based on the Xie and Stevenalgorithm is presented. With this algorithm a fully stresseddesign is obtained by a gradual removal of low…

An anisotropic elastoplastic model based on an isotropic formulation

S. Oller, S. Botello, J. Miquel, E. Oñate

This paper shows a generalization of the classic isotropic plasticitytheory to be applied to orthotropic or anisotropic materials. This approachassumes the existence of a real…

Parameter sensitivity of elastoplastic response

M. Kleiber, T.D. Hien, H. Antúnez, P. Kowalczyk

The general problem of sizing, material and loading parameter sensitivity of non‐linear systems is presented. Both kinematic and path‐dependent material non‐linearities are…

Application of porous media mechanics to the numerical simulation of the rolling of sugar cane

D.R.J. Owen, S.Y. Zhao, J.G. Loughran

A finite element solution to the rolling of two‐phase materials ispresented and applied to the rolling of prepared sugar cane. The generalizedBiot theory is extended and modified…
