This textbook gives an introduction to all three classes of geometry optimization problems of mechanical structures: sizing, shape and topology optimization. The style is explicit and concrete, focusing on problem formulations and numerical solution methods.
The treatment is detailed enough to enable readers to write their own implementations. Generally, the aim is to achieve one such design that produces a optimized structure that is stiff enough to support the mechanical load and compliant enough in proper areas to release the thermal stress.

the position and arrangement of structural elements can influence the structural behavior fundamentally. A topology optimization must therefore be carried out in a very early stage of the design process.

Shape optimization is an extension of the previously developed concepts, and it considers not just straightforward dimensional changes, but general changes in shape as well. The shape of the structure is controlled via a set of design parameters that use a set of basis functions, which can describe quite arbitrary shapes.
The shape optimization problem consists in looking for the geometry that minimizes an objective function, like mass or compliance, subject to mechanical constraints. The boundary element method (BEM) is used for the structural analysis.
For linear elasticity problems, it needs only a mesh on the boundary of the structure. This work addresses various mathematical solution strategies adapted for design optimization of multiphase materials.
The goal is to improve the structural performance by optimizing the distribution of multiple phases that constitute the material. Examples include the optimization of multiphase materials and composites with spatially varying fiber paths using a finite element analysis by: 1.

Shape Optimization is a powerful aspect of product simulation that intelligently drives the shape of parts - improving robustness and efficiency. VR&D software enables engineers and scientists to efficiently analyze, design and improve structures.
In the automated design of mechanical systems by means of structural synthesis techniques, two cathegories of procedures, namely shape and sizing optimization, play different but equally important roles: the former is usually applied to the synthesis of solid modelled (in the finite element method sense) structures, by finding optimum positions for the model's nodes, and the later Author: Sergio Butkewitsch, Valder Steffen, Marcos Antônio Argentino.Shape optimization is part of the field of optimal control theory.
The typical problem is to find the shape which is optimal in that it minimizes a certain cost functional while satisfying given many cases, the functional being solved depends on the solution of a given partial differential equation defined on the variable domain.Topology optimization (TO) is a mathematical method that optimizes material layout within a given design space, for a given set of loads, boundary conditions and constraints with the goal of maximizing the performance of the system.
TO is different from shape optimization and sizing optimization in the sense that the design can attain any shape within the design space, instead of dealing with.
