Structural optimization deals with optimal design of load-carrying structures.
The purpose of this project is to develop mathematical models and efficient numerical methods for different types of structural optimization problems. Here follows a brief summary of our research during the year. First, we have studied the trajectories of optimal solutions to penalized or relaxed topology optimization problems as the penalization- or relaxation parameter is varied. Second, we have developed a new artificial material interpolation model, defining stiffness as a certain rational function of density.
