Introduction to Structural Optimization and Its Potential for Development of Vehicle Safety Structures
The purpose of this chapter is to present specific structural optimization techniques. This is an extension of Chapter 3, which presented general optimization techniques. This chapter firstly addresses topology optimization including aspects such as relaxation, the checkerboard effect, the variable density method (VDM) the solid isotropic material with penalization (SIMP) interpolation schema, the sum of reciprocal values (SRV) constraint, design sensitivity analysis (DSA) and homogenization based optimization (HBO) The chapter then focuses on three main methods for shape optimization: the Lagrangian approach, the Eulerian approach, and morphing.
