A practical error estimator in elastoplastic problems with large strains. Part I: theoretical development

A. Hernández, Ch. Pinto, J. Albizuri, O. Altuzarra

This paper focuses on the study of finite element (FE) analysis reliability of non‐linear planar structural problems (large strains and plasticity). In this first part, some error…

A practical error estimator in elastoplastic problems with large strains. Part II: analysis of numerical results

Ch. Pinto, R. Avilés, J. Albizuri, A. Hernández

In this second part of the paper, some properties of the discretization error estimators are presented, although their theoretical background was already developed in the first…

Viscoplastic D/BEM analysis of metallic structures with dependence on thermomechanical history

C.P. Providakis, S.G. Kourtakis

The feasibility of advanced viscoplastic models for non‐linear boundary element analysis of metallic structural components with dependence on thermomechanical history is…

Non‐linear explicit dynamic analysis of shells using the BST rotation‐free triangle

E. Oñate, P. Cendoya, J. Miquel

The paper describes the application of the simple rotation‐free basic shell triangle (BST) to the non‐linear analysis of shell structures using an explicit dynamic formulation…

A new point creation scheme for uniform Delaunay triangulation

J. Muylle, P. Iványi, B.H.V. Topping

A new point creation scheme is presented for generating unstructured uniform size two‐dimensional triangular meshes using the Delaunay triangulation method. The scheme is shown to…
