A simple triangular curved shell element

H. Stolarski, T. Belytschko, N. Carpenter, J.M. Kennedy

A simple triangular shell element which incorporates the effects of coupling between membrane and flexural behaviour and avoids membrane locking is described. The element uses a…

Pseudo 3‐D projections from isoparametric surfaces

D.J. Byrne

Graphical representations play an integral part in the interpretation of the numerical data, resulting from finite element analysis techniques. An algorithm is presented for the…

A simple but effective method to produce colour FEM result presentations

J.F. Stelzer

Today, many computer screens offer colour. It is easy to take advantage of this when working with isoparametric elements. It is shown how to adjust suited colours to element…

A Galerkin boundary element formulation with moving singularities

P.S. Han, Olson, R.L. Johnston

In conventional boundary element formulations, the singularities of the fundamental solution are usually located on the problem boundary. This leads to difficulties in evaluating…

Sensitivity studies in reliability‐based plastic design

Dan M. Frangopol

The paper attempts to establish the connection between structural reliability and structural optimization for the particular case of plastic structures. Along this line, the paper…

Generalized time finite element algorithm for non‐linear dynamic problems

Jerzy Kujawski, Chandrakant S. Desai

A generalized time finite element method is considered for time integration of non‐linear equations of motion arising from dynamic problems. A simple three‐time level family of…

Selecting non‐linear optimization techniques for structural design

B.H.V. Topping, D.J. Robinson

The use of three non‐linear mathematical programming techniques for the optimization of structural design problems is discussed. The methods — sequential linear programming, the…

Eulerian—Lagrangian solution of convection dominated diffusion problems

Vincenzo Casulli

Some existing finite difference methods for the numerical solution of convection dominated diffusion equations are compared. Two semi‐implicit methods, Lagrangian based and…

Linear elastic and non‐linear elastoplastic plate bending analysis using a mixed Galerkin finite element technique

Y.W. Kwon, J.E. Akin

The mixed finite element formulation using the Galerkin method is developed for the small deflection of a plate. This equation requires only linear shape functions to give…

An interactive contour plotting program

Michael F. Yeo

A very fast interactive contour plotting package is presented. Any finite element mesh is automatically converted into a contour plotting mesh composed of 3‐noded triangular…
