An efficient flexurally superconvergent hexahedral element

Xiao‐Jun Wang, Ted Belytschko

A hexahedral 8‐node element based on the Hellinger—Reissner principle is formulated with the γ projection operator so that it can achieve engineering accuracy for plate and beam…

Re‐analysis procedure based on the mixed formulation

Ahmed K. Noor, Jeanne M. Peters

A simple and efficient re‐analysis procedure is presented for large‐scale structural systems. The procedure is based on using a mixed formulation with the fundamental unknowns…

Plasticity computations using the Mohr—Coulomb yield criterion

M.A. Crisfield

The paper describes the derivation and application of a range of numerical algorithms for implementing the Mohr—Coulomb yield criterion in a non‐linear finite element computer…

Generation of load dependent Ritz transformation vectors in structural dynamics

P. Léger, E.L. Wilson

The evaluation of linear dynamic response analysis of large structures by vector superposition requires, in its traditional formulation, the solution of a large and expensive…

Finite element analysis of reinforced rubber shells

J.M.A. Cesar de Sa, D.R.J. Owen

The application of numerical techniques to the solution of practical problems which exist in rubber technology is described. Structures and components in the form of reinforced…

Rate form of the equation of state for thermalhydraulic systems: numerical considerations

W.J. Garland, R. Sollychin

In conjunction with the usual rate forms of the conservation equations, the time derivative form of the equation of state is investigated from a numerical consideration point of…

Dynamic analysis and modelling of heavy machinery foundations

Francisco Medina, J. Estay, M.O. Moroni
