Shape optimization with the biological growth method: a parameter study

A. Erman Tekkaya, Alper Güneri

Studies the effect of parameters controlling the biological growth method by applying it to the classical optimization problem of a plate with a central hole under biaxial stress…

Predicted natural frequencies of two‐dimensional elastodynamic problems: a practical error estimator

Chongbin Zhao, G.P. Steven

Based on the asymptotic solution for predicted natural frequencies of a two‐dimensional elastodynamic problem from the finite element analysis, presents the concept of the…

Integration algorithms for concrete plasticity

G. Etse, K. Willam

Presents a computational algorithm for the numerical integration of triaxial concrete plasticity formulations. The specific material formulation at hand is the so‐called extended…

The reconstruction of boundary contours and surfaces in arbitrary unstructured triangular and tetrahedral grids

N.P. Weatherill

In an arbitrary assembly of triangles or tetrahedra there is often a requirement to recover or construct edges or triangles which are formed by the connections between nodes. Such…

Three‐dimensional finite element simulation of creep deformation in rock salt

J.R. Weatherby, D.E. Munson, J.G. Argüello

Describes a set of numerical techniques which implement the rate‐dependent multi‐mechanism deformation (M‐D) constitutive model for rock salt in a finite element code for use in…
