Model‐size reduction for the non‐linear dynamic analysis of quasi‐symmetric structures

Ahmed K. Noor, Jeanne M. Peters

A computational procedure is presented for the efficient non‐linear dynamic analysis of quasi‐symmetric structures. The procedure is based on approximating the unsymmetric…

A hypermatrix formulation for subspace iteration

Richard J. Schmidt, Robert H. Dodds

The computational efficiency of subspace iteration is addressed relative to the data structures adopted for the very large and generally sparse coefficient matrices. The…

Numerical solution of the elastohydrodynamic problem in soft reciprocating seals

Antonio Strozzi

A class of exact solutions to the elastohydrodynamic problem to be used as test cases is presented. A numerical solution to the elastohydrodynamic problem according to the…

An improved 9 DOF Hybrid—Trefftz triangular element for plate bending

A. Venkatesh, J. Jirousek

This paper presents a new 9 DOF triangular element for plate bending. It is an analytically integrated improved version of the simplest member in the hierarchy of…

A solution algorithm for the finite element analysis of creep problems

N.J. Marais, J.B. Martin

A solution algorithm for the transient analysis of bodies undergoing creep under constant or time varying loads is presented. The constitutive equation adopted is of the…

Assumed strain stabilization procedure for the 9‐node Lagrange plane and plate elements

Bak Leong Wong, Ted Belytschko

An alternative stabilization approach has been developed for the 9‐node Lagrange plane and plate elements. In this approach, a stabilization stiffness is formulated using…

An improved subroutine for the estimation of torsional properties of thin walled open cross‐sections

J.P. Coyette

This paper suggests some improvements to the computer‐aided estimation of the torsional properties of open cross‐sections as presented in a previous paper. The complete…

Application of computational plasticity to the analysis of vehicle cab frames

Christopher F. Kearns

The application of computational plasticity to the very practical engineering problem of crash‐worthiness of vehicle safety cab frames during impact and rollover incidents…

Calculation of shear and moment envelopes by Macauley's method

C.J. Burgoyne

The paper describes the use of a microcomputer to determine the behaviour of continuous beams. Three procedures are described: the analysis of continuous beams subject to…
