The present paper’s main objective is to derive a simple upper bound solution for a welded plate in pure bending. The plate contains a crack located in the weld. Both the weld and base materials are orthotropic. Hill’s quadratic yield criterion i

The paper extends Orowan’s method to the prediction of ductile fracture in plane strain rolling. In general, any uncoupled ductile fracture criterion can be used in conjunction with the solution found. However, the present paper focuses on a ductil

Previous theoretical work has shown that frictionless dies can be designed to produce maximum efficiency in the reduction of isotropic rigid perfectly plastic strip under plane strain conditions. This is accomplished by contouring the die to cause co

This paper presents an elastic/plastic model that neglects strain hardening during loading, but accounts for the Bauschinger effect. These mathematical features of the model represent reasonably well the actual behavior of several materials such as h

Planar flow of an incompressible rigid plastic material obeying a special case of the double slip and rotation model is studied in the vicinity of an envelope of characteristics. An orthogonal coordinate system whose base vectors are normal and tange

The objective of the present work is to develop a method of finding principal stress trajectories in pressure-independent and pressure-dependent plasticity under plane strain and plane stress conditions. It is shown that the geometry of the principal

A semi-analytic solution for the elastic/plastic distribution of stress and strain in a spherical shell subject to pressure over its inner and outer radii and subsequent unloading is presented. The Bauschinger effect is taken into account. The flow t

A semi-analytic solution for the elastic/plastic distribution stress and strain in a thin annular disc subject to pressure over its inner radius is presented. It is assumed that a pressure-dependent yield criterion and its associated flow rule are va

A comparative study of two analytic solutions for the classical plasticity of incompressible materials and a plasticity model for powder materials is made to reveal an effect of plastic compressibility on qualitative behaviour of the velocity field i
