✦ Synopsis

A finite-difference procedure which requires the use of ¨irtual and duplicate nodes is presented. This procedure incorporates the Neumann and Dirichlet boundary conditions into the two-dimensional Helmholtz equation. Comparisons made with analytic solutions for wa¨eguide modes indicate that robust solutions can be obtained with a low mesh density.

A new simpler solution procedure is presented for the finite element analysis of creep problems. The creep strains are eliminated as computation variables. At each time step, a system is solved for the stresses and velocities alone.

A finite difference perturbation scheme is developed which allows a simple solution to a wide class of non-linear bifurcation problems. The analysis shows that in order to determine the initial post buckling behaviour accurately, it is not necessary to solve more than the linear eigenvalue differenc
