A Powerful Finite Element Method for Low Capacity Computers
The progress made in computer hardware over the last decades has lead to the development of fairly powerful mini-computers and for some time now there has been a strong demand to develop special versions of the existing FE programs for their use. For obvious reasons, the practical application of conventional finite elements on micro-computers should, however, be limited to comparatively simple problems which may be solved with adequate accuracy by using relatively few elements and a low total number of degrees of freedom. The method of Large Finite Elements (LFE) removes this difficulty and enables to extend the range of practical applications to involved problems including various stress concentrations and/or stress singularities.
