Finite element analysis of a wing type structure with experimental verification of results.

[摘要] INTRODUCTION: The advent of the high speed computer has revolutionized structuraldesign in all spheres of Engineering. Up till then structural stressanalysis was limited to over-simplification of the structure in question to comply with derived classical mathematical solutions.In practice however the picture is very different, the structureusually being complex and highly redundant in nature. The techniquesinvolving Energy Methods to solve such structures have been known fora long time. However they required weeks of hand calculations tosolve only a small number of redundancies in a structure. Neville Shutementions this in his book Slide Rule.The development of Matrix algebra and the finite element method has madeit possible to analyse, say, a complete aircraft structure in a matterof days. using a large capacity high speed computer~Experimental results have shown that finite element stress analysis comesmuch closer to reality than the dated classical methods.
