NON-LINEAR FINITE ELEMENT ANALYSIS OF SHELLS USING PARAMETRIC STUDY

The shells are the structural elements which are characterized by their geometry. Which can replace heavy slabs for the roofing of a building at a large height. They also provide a large column free area. The strength of the shell is through its geometry and not through its mass. Thus, it provides less amount of building materials. So the non-linear finite element analysis of the shells help us to know their behavior after the elastic limit. A reliable nonlinear finite element analysis of shell structures, there are two main ingredients to be considered i.e., formulation of appropriate shell element and development of numerical algorithms for solving the equations of motion. The study is performed on a Finite element analysis based software i.e., ANSYS. The non-linear analysis is performed by parametric study in which different parameters of the shells are changed and the result is analysed and is compared with the analytical results from previous papers. As there is rapid increase in the use for thin shells for the construction to reduce the amount of materials providing the same strength, this study is helpful for the construction industry.
