Computations of an engine to analyze cylinder distortion

Ali Soua, Maurice Touratier, Laurent Polac

The aim of the research work presented here is to control the geometric distortions of engine cylinders, which involve both noise and oil consumption. The final goal is then to…

Object oriented programming via Fortran 90

J.E. Akin

There is a widely available object oriented (OO) programming language that is usually overlooked in the OO analysis, OO design, OO programming literature. It was designed with…

On the integration of stresses in large deformations plasticity

A.F. Marcon, E. Bittencourt, G.J. Creus

Discusses an alternative formulation for the incremental determination of stresses in strain measures that can be used to replace the stress rates currently employed. The…

Performance of low‐order triangular elements during plastic flow

O.M. Heeres, R. de Borst

An important characteristic of many soil models is a volume change during plastic flow. In computations, this plastic volume change is expressed via a kinematic constraint on the…

A superlinear convergent augmented Lagrangian procedure for contact problems

G. Zavarise, P. Wriggers

The numerical solution of contact problems via the penalty method yields approximate satisfaction of contact constraints. The solution can be improved using augmentation schemes…

An algorithm for domain partitioning with load balancing

G.P. Nikishkov, A. Makinouchi, G. Yagawa, S. Yoshimura

An algorithm for domain partitioning with iterative load balancing is presented. A recursive graph labeling scheme is used to distribute elements among subdomains at each…
