Structural topology optimization: from minimizing compliance to maximizing energy absorption (original) (raw)

This is a review paper describing the evolution of the subject of topology optimization of continuum structures since 1988. The basic idea of posing the optimization problem as a distribution of material is being compiled and presented here. The subject has matured from minimization of compliance in simple two-dimensional elastostatics problems to maximization of energy absorption in complex three-dimensional shell-like structures subject to structural deformation beyond the linear limit. Some examples from the automotive industry are presented to illustrate the review. Structural topology optimization is an important tool for structural designers. In the first half of the 20th century, new structural designs were obtained using much of the experience of the designer. However, with the introduction of structural optimization in the early 1960s, plus advances in topology optimization in the 1990s, design processes have changed. Computers have helped to create new topological designs ...
