Level set topology optimization based on isogeometrical formulation of plane elasticity problems

In this paper a level-set approach to topology optimization is presented where level set function is parameterized using non-uniform rational basis splines (NURBS). Isogeometrical numerical method is used for calculating objective function, i.e. for performing structural analysis. Objective function is based on minimizing compliance to find the optimal distribution of material in the design domain under a specified volume constraint. Two benchmark examples are presented to illustrate the method.
