A velocity approach to finite element calculation of elastoplastic and viscoplastic deformation processes
J.L. ChenotThe constitutive equations for the deformation of elastoplastic, viscoplastic or compressible materials are presented for the small strain approximation and for the large…
Non‐linear stability analysis of structures under multiple parameter loads
Zenon Waszczyszyn, Czestaw CichońAn extended set of equations is formulated. The set is a combination of incremental FEM equations, constraint equations and an augmented equation corresponding to the…
Semi‐loof shell, plate and beam elements—new computer versions: Part 1. Elements formulation
R.A.F. Martins, C.A.M. OliveiraThe semi‐loof element is probably one of the most efficient for the solution of thin shells of arbitrary geometry. It was originally published by Irons and since then it…
Semi‐loof shell, plate and beam elements—new computer versions: Part 2. Elements programming
R.A.F. Martins, C.A.M. OliveiraAccording to Figure 1, semi‐loof shell, plate and beam elements are implemented in such a way that three independent blocks are formed to obtain the stiffness, mass, load…
Error indicators and accuracy improvement of finite element solutions
Ahmed K. Noor, Jeanne M. PetersError indicators are introduced as part of a simple computational procedure for improving the accuracy of the finite element solutions for plate and shell problems. The…
Elastic stability of plates with and without openings
I.M. May, T.H. GanabaThe finite element method of analysis is used to determine the elastic buckling loads for plates with and without openings. The formulation is based on Mindlin plate…
Numerical analysis of fire effects on beam structures
R. Contro, C. Poggi, A. CazzaniA known finite element model is significantly enriched in order to take into consideration the variations of material parameters that are provoked by elevated temperatures…
Axisymmetric thermoelasticity by combined boundary and finite elements
Thomas J. RudolphiThe boundary element and finite element methods have been combined so as to allow for arbitrary intermixing of element types in modelling problems of axisymmetric…
A viscoplastic model for soft rock
M.B. ReedThe aim of the model is to represent the main features of soft or brittle rock strata, using a small number of physically‐meaningful material parameters. The yield surface…
Comparison of four finite element solutions of self‐adjoint and non‐self‐adjoint problems governed by differential equations with predominant lower order derivatives
A.E. Kanarachos, C.N. SpentzasConsidering typical self‐adjoint and non‐self‐adjoint problems that are governed by differential equations with predominant lower order derivatives, a comparison is…
Multi‐variable finite element algorithm based on the generalized Galerkin method
J.Y. Zhang, T.R. HsuA multi‐variable finite element algorithm based on the generalized Galerkin method is presented. This algorithm takes advantages from the hybrid finite element method and…
Inclusion of transverse normal strain effects into the finite element formulation of Timoshenko beams
Hamdy H. Abdel‐Rahman, Mohammed H. Baluch, Ali I. Al‐HejjiA new finite element model has been developed for the analysis of thick beams that incorporates the influence of transverse normal strain in addition to the effect of…
