Finite element and Ritz vector techniques for the solution to three‐dimensional soil — structure interaction problems in the time domain

E. Bayo, E.L. Wilson

A general time domain finite element formulation and several efficient numerical techniques are combined to form a new method of analysis for the solution of three‐dimensional…

An algorithm for assembly of stiffness matrices into a compacted data structure

Bahram Nour‐Omid, Robert L. Taylor

A data structure is described that stores only the non‐zero terms of the assembled stiffness matrix. This storage scheme results in considerable reduction in memory demand during…

Geometrically non‐linear analysis of thin plates and shells using a generalized displacement method

Li Xi‐Kui, Guo‐Qiang Liu, D.R.J. Owen

A generalized displacement method has been previously presented for the analysis of thin plate‐shell structures with the use of bilinear 4‐node isoparametric shell elements…

Finite element analysis of plate systems: 1. Hybrid—mixed finite elements

I. Vayas

The analysis of plate systems (Figure 1) with mixed finite elements is limited to geometric smooth partial systems (Figure 1a) with continuous strains and stresses. This is due to…

Finite element analysis of plate systems: 2. Geometric and material non‐linear behaviour

I. Vayas

During the 1970s 4 steel bridges in Australia, England, Austria and Germany, failed due to the buckling of their compressed plates. As a result of these failures much research…

Computerized generalized displacement method for finite element analysis of incompressible material

Li Xi‐Kui

A new approach to deal with the finite element analysis of incompressible material is presented. The constrained variational problem relating to the analysis of incompressible…

Use of substructuring in non‐linear material analysis

T.K. Hellen

The latest release of the stress analysis finite element system BERSAFE contains a new general substructuring facility for use in either elastic or non‐linear analysis. The…

Transient large strain analysis of plane and axisymmetric structures by means of biquadratic finite elements

J.P. Halleux, F. Casadei

A finite element procedure is presented for refined transient analysis of two‐dimensional (plane or axisymmetric) non‐linear structures involving arbitrarily large displacements…

Large deflection formulations of a simple beam element including shear deformations

Lothar Haefner, Kaspar J. Willam

A simple beam element is developed for the solution of large deflection problems. The total Lagrangian formulation is based on the kinematic relations proposed by Reissner for…

A nine node Lagrangian Mindlin plate element with enhanced shear interpolation

H.C. Huang, E. Hinton

This paper presents an improved nine node Mindlin plate element. An enhanced interpolation of the transverse shear strains is used in this formulation of the new element which has…

Analysis of steel orthotropic deck plates in the non‐elastic state under variable loads

Zbigniew Mańko

Steel orthotropic bridge deck plates have a remarkable reserve of carrying capacity which should usefully be studied further in practice. This paper shows the application of the…
