On the computational efficiency and implementation of block‐iterative algorithms for nonlinear coupled problems

M. Cervera, R. Codina, M. Galindo

Outlines a general methodology for the solution of the system of algebraic equations arising from the discretization of the field equations governing coupled problems. Considers…

FE modelling of a boundary layer corrector for composites using the homogenization theory

M. Lefik, B. Schrefler

Using finite element (FE) method corrects the microstress field resulting from the theory of homogenization in the region of composite in vicinity of the boundary. Obtains the…

An inverse thermal field problem based on noisy measurements: comparison of a genetic algorithm and the sequential function specification method

R.L. Wood

Draws a comparison between the use of a genetic algorithm and the sequential function specification method for the solution of a one‐dimensional linear inverse thermal field…

An energy‐conserving planar finite beam element for dynamics of flexible mechanisms

Nielen Stander, Erwin Stein

Using examples of flexible mechanisms, demonstrates that while the Newmark method is unstable for nonlinear dynamics, time step refinement could in some cases lead to even earlier…

DYNROT: a finite element code for rotordynamic analysis based on complex co‐ordinates

G. Genta, C. Delprete, D. Bassani

DYNROT is a code based on the finite element method which is intended to perform a complete study of the dynamic behaviour of rotors. Although initially designed to solve the…

Instabilities induced by coarse meshes for a nonlinear shell problem

M.A. Crisfield, X. Peng

Presents a range of numerical results obtained from the geometrically nonlinear analysis of a cantilevered cylindrical shell. Shows that, while the fine‐mesh solution involves no…
