|Title:||Structural shape optimization of 3D nearly-incompressible hyperelasticity problems|
|Abstract:||This paper presents shape optimization of nearly incompressible hyperelastic structural problems. Initially, the Mooney-Rivlin hyperelastic model is reviewed. The finite element solution using a perturbed Lagrangian description and the Newton-Raphson method are discussed. The projected pressure method is used to solve the mixed problem using a standard one-field finite element procedure. The expressions of shape sensitivity are presented. Finally, the shape optimization of an engine mount creometry is considered using 2D and 3D finite element models.|
