A review of expert systems development tools
J. MackerleExpert systems are being effectively applied to a variety of engineering problems. A growing number of languages and development tools are available for their building. Expert…
Approximations to non‐normal random variables in structural reliability analysis
Karl V. BuryModern reliability analyses of large structural system designs require substantial computing times, and need to be repeated frequently in the process of design optimization. In…
Graphical postprocessing for 3‐D mesh quality evaluation
M.J. Panthaki, J.F. Abel, P.A. WawrzynekAn important objective of 3‐D graphical finite element postprocessing is the facility to indicate to the engineer the accuracy of analysis results. The inclusion of mesh quality…
Post‐processing techniques for assessing element distortion errors
M. Ulbin, T.K. HellenFinite element meshes can today be used to represent very complex structures because of high performance hardware and software. Although a very successful contributor to modern…
Maguerre‐Mindlin shallow shell elements
Gerhard KrauseTwo isoparametric Lagrangian shallow shell elements are presented: a 4‐node element QUAD4 and a 9‐node element QUAD9. These elements are based on Mindlin/Reissner plate elements…
The WYD method in large eigenvalue problems
Mingwu Yuan, Pu Chen, Shanji Xiong, Yuanneng Li, Edward L. WilsonThe advantages of a direct superposition of the Ritz vector in dynamic response analysis (developed by Wilson, Yuan, and Dickens in 1982 and termed the WYD method) are that: no…
An assessment of assumed strain methods in finite rotation shell analysis
Nielen Stander, Anton Matzenmiller, Ekkehard RammA critical assessment of the 4‐node assumed strain element as proposed by Dvorkin and Bathe is made. The element performed excellently in all investigated shell problems which…
Exact evaluation of contact stress state in computational elasto‐plasticity
Nenad Pankaj BicanicVarious stress return algorithms in elastoplastic analyses using the finite element method require the evaluation of the contact (or penetration) stress state (Figure 1), defining…
Simple finite element codes in Occam on a transputer
Peter Bettess, Martin J. DownieIn recent years attention has turned from conventional ‘von Neumann’ computers to totally new computer architectures. Many surveys of these developments are available and a number…
