Towards effective interactive three‐dimensional colour postprocessing

Bruce C. Bailey, Jerome F. Hajjar, John F. Abel

Recommendations for the development of effective three‐dimensional, graphical colour postprocessing are made. First, the evaluation of large, complex numerical models demands that…

Design and testing of deep water sealine connector with non‐linear finite element analysis

S. Giuli, F. Trave

Analyses were performed during the conceptual design stage of a 20in. threaded connector for deep water J‐pipe lay, as part of a research project developed by Tecnomare and partly…

Perturbation technique with characteristics in convection‐dominated flows with small diffusion and dispersion

H.M. Cekirge, R.J. Fraga

The proposed method utilizes characteristics to model convection and perturbation technique for diffusion and dispersion. Thus, each physical process is treated by a numerical…

Computer‐automated design of structural systems under reliability‐based performance constraints

Dan M. Frangopol

Optimization of structural systems under reliability‐based performance constraints is an important problem at present receiving too little attention. This problem is investigated…

Pseudo‐corner theory: a simple enhancement of J2‐flow theory for applications involving non‐proportional loading

Thomas J.R. Hughes, Farzin Shakib

A simple modification of J2‐flow theory is made which enables it to approximately represent the reduced stiffness and increased plastic flow of corner‐theory response to…

Efficient non‐linear finite element shell formulation involving large strains

Horst Parisch

A previously presented finite element shell formulation is extended to the application of large strains. The finite elements are those based on the concept of ‘the degenerated…

Shear forces and twisting moments in plates using Mindlin elements

E. Hinton, H.C. Huang

Finite elements based on Mindlin plate theory are used to study the distribution of shear forces and twisting moments on the boundaries of plates with various support conditons…

Numerical techniques for cyclic plasticity at variable temperature

H. Burlet, G. Cailletaud

A formulation of non‐linear kinematic hardening in plasticity is given, with a short description of the model properties under cyclic loading. A resolution algorithm based on the…

CALFEM — a program for computer‐aided learning of the finite element method

Ola Dahlblom, Anders Peterson, Hans Petersson

A computer program, CALFEM, is presented. This interactive computer program is designed as a tool for teaching of the finite element method. No programming knowledge is needed…

A microcomputer solution of Biot's two‐dimensional consolidation theory

H.R. Thomas, C.H. Liu

The implementation of the finite element solution of Biot's consolidation theory on a low‐cost microcomputer is described. A two‐dimensional linear elastic model is solved using…
