Finite element analysis of composite beams

Abstract

In Finite Element analysis the size of mesh plays a critical role. It is closely said that accuracy and number of mesh required for the meshing of the element. This paper presents the effect of the von misses and various constraints on the accuracy of the result. On the basis of the papers referred and guidelines obtained for choosing the appropriate mesh size in finite element analysis has been provided and explained about the von misses stress occurred in the model. The web reinforcement should be strengthened enough to carry tension forces as well as compression forces so that the compression wrinkling is avoided. Von mises proves to be the perfect safe value for the designing of composite structures which involves various stress theories and failure criteria.
