Isogeometric analysis bridges the gap between the fields of CAD (Computer-Aided Design) and CAE (Computer-Aided Engineering) with the concept that the NURBS(Non-Uniform Rational B-Spline) basis function widely used for geometry description is employed to approximate the field variables such as nodal displacement, stress and strain in FEA(Finite Element Analysis). The problems in linear elasticity are the original examples successfully solved by finite element analysis and still occupy a large part of industrial applications, therefore we apply the method of IGA (isogeometric analysis) to solve this problem and proved the effectiveness of this newly invented approach.
Keywords:Computer Application; IGA; CAE
