Topological Shape Optimization of Multiphysics Actuators using Level Set Method

This paper proposes a topological shape optimization method for the design of multi-physics piezoelectric actuators using a level set method of piecewise constants. A level set function taking level sets of piecewise constants is applied to implicitly represent design boundaries in a multiphase design domain, in which each constant level set denotes one material phase. As a result, only one lev...

Shape optimization with a level set based mesh evolution method

We intend to propose a framework to handle the problem of mesh deformation in the context of shape optimization. The main idea is to combine the level set method with meshing tools specialized to deal with implicitly-defined geometries. The proposed method is then as well a topology optimization as a geometric optimization method.

A level-set method for shape optimization

We study a level-set method for numerical shape optimization of elastic structures. Our approach combines the level-set algorithm of Osher and Sethian with the classical shape gradient. Although this method is not specifically designed for topology optimization, it can easily handle topology changes for a very large class of objective functions. Its cost is moderate since the shape is captured ...

CAD-Based Shape Optimization Using a Meshfree Method

A shape design sensitivity analysis and optimization procedure is proposed using a meshfree method. A CAD tool connection is established to facilitate the seamless integration of structural modeling, simulation, and design optimization. A new CAD-based method for design velocity computation is proposed, applicable to both the meshfree method and the finite element method. A shape design variabl...

Structural optimization using topological and shape sensitivity via a level set method

A numerical coupling of two recent methods in shape and topology optimization of structures is proposed. On the one hand, the level set method, based on the classical shape derivative, is known to easily handle boundary propagation with topological changes. However, in practice it does not allow for the nucleation of new holes (at least in 2-d). On the other hand, the bubble or topological grad...
