Abstract
Dynamic Relaxation and Finite Elements are probably the most common methods for structural analysis of 2, 2.5 and 3-D continua. Historically FE had a marked advantage in cost and accuracy. Today, when personal computers are universally available, an improved version of DR, called PV, has significant advantages. These are: Simplicity, by which any engineer can understand and apply the programs without risk of error. Versatility, by which the simple principles can easily be used to analyse folded plate structures, shells, dynamic loads, etc. Storage Economy, by which full 3-dimensional structures can be analysed with a personal computer. PV has particular advantages when analysing structures which are non-linear owing to cracking and/or yielding. It has no stiffness matrix, and it permits a very realistic and accurate analysis of multi-axial yielding.
