Inverse Problems in Science and Engineering. 20:735-748
This investigation concerns an inverse problem modelled by the finite element method. For a given mesh and set of physical properties, even though a well-posed direct problem possesses a unique solution in classical linear elasticity, variational arg

Baseline data is produced for designing an optimum Defense Hole System (DHS) for a large plate with a circular hole in shear dominant-load range. Stress concentration associated with circular holes for tensile/shear ratio ranging from 0% to 25% is re

For time integration in finite element analysis, a higher order counterpart of the widely used Newmark method is formulated by applying the three step fourth order Adams-Moulton (AM) method to lightly damped systems with accelerations. A linear syste

A stability analysis of a delaminated beam subjected to a follower compressive load is presented. The beam is fixed at its left end and restrained by a translational spring at its right end as this specific configuration of beam subjected to follower

Arc length constraints enable iterative solution procedures in nonlinear finite element analysis to converge even at critical points. The arc length constraint replaces the conventional m×m stiffness matrix with an augmented (m+1)×(m+1) stiffness m

In many problems in nonlinear solid mechanics, the finite element method is executed incrementally, with the positive definite stiffness matrix updated after one or more load (or time) increments. In solving the resulting large linear perturbed syste

Finite-element equations for incompressible and near-incompressible media give rise to a matrix with a diagonal block of zeroes or very small numbers. The matrices are not amenable to conventional techniques involving pivoting on diagonal entries. Uz

A stress is considered conjugate to a strain if the product of the stress and an objective rate of the strain has a trace which is equal to the rate of work per unit volume. Using Kronecker product relations, apparently new expressions for stresses c

Stress concentrations associated with circular holes in pure shear-loaded plates can be reduced by up to 13.5 per cent by introducing elliptical auxiliary holes along the principal stress directions. These holes are introduced in the areas of low str
