Improvement of C0 vibration problems using Helmholtz equation to recover nodal gradients

Chin‐Hsu Lin

The paper presents a method for the more accurate solution of C⁰ acoustic vibration problems in finite element (FE) analysis by postprocessing. For each frequency, the method uses…

A refined numerical approach for the ultimate‐load analysis of 3‐D steel rod structures

Norbert Gebbeken

As far as steel‐rod structures are concerned the yield‐hinge theory is a very efficient approach of the ultimate‐load theory. Unfortunately, most of the published strategies…

Recent developments in the incremental flow formulation for the numerical simulation of metal forming processes

Javier Bonet

This paper describes the use of the incremental flow formulation for the numerical analysis of forming processes. This formulation is based on the approximation of the flow type…

Mesh generation over curved surfaces with explicit control on discretization error

S.H. Lo, T.S. Lau

A scheme is presented for the automatic generation of triangular meshes over general analytical curved surfaces with explicit control on the discretization error over the interior…

Shape representation and contact detection for discrete element simulations of arbitrary geometries

Caroline Hogue

When simulating the behaviour of granular assemblies and multi‐body systems using a discrete element analysis, the shape representation of the bodies and the contact detection…

Design sensitivity analysis method for multidisciplinary shape optimisation problems with linear and non‐linear responses

G. Chiandussi, R. Fontana, F. Urbinati

A method to solve shape and size optimisation problems with linear and non‐linear responses has been studied taking advantage of statistical methodologies. A nested optimisation…
