Abstract

In this paper, the authors present an illustratived step by step approach to perform Isogeometric analysis (IGA). The existing literature does not have any solved problems in a stepwise procedure, which can be useful to explain in a classroom. This paper should serve as a benchmark example to refer the stepwise procedure to learn IGA. The focus is on the illustrative stepwise analysis and Isogeometric analysis using NURBS basis functions (Non-Uniform Rational), which can represent the Geometry of the structure more precisely over the finite element method. In this paper, a two dimensional plane plate structure carrying in-plane loading is analysed using Isogeometric analysis. The problem is also solved using Marc Mentat®, a finite element package and the results are compared and presented. The results show that the nodal displacements calculated using Isogeometric analysis are in close agreement with the nodal displacements found using a standard finite element package.
