Abstract:
NURBS(Non-Uniform Rational B-Splines) is currently the most commonly used mathematical language in CAD and computer graphics for creating geometrical models. In the spline finite element methods, NURBS is used both for the discretization of the analysis models and for the approximation of field variables. 

In this way, the time and efforts in creating analysis models can be significantly reduced. Moreover, the features of splines can be effectively exploited in the shape/topology optimization making it possible to streamline the product design process. 

In this presentation, it will also be shown how the features of spline finite element method combined with TSA (Trimming Surface Analysis) can be exploited for the shape/topology optimization of structures. Also a meshfree method contrived by employing TSA in the spline finite element method will be explained. Some applications of the meshfree method will be presented through numerical examples.
