Designing Manufacturable Viscoelastic Devices Using a Topology Optimization Approach Within a Truly-Mixed Fem Framework

Abstract

A new approach to topology optimization is presented that is based on the minimization of the input/output transfer function H ∞ norm. Additionally, by properly selecting input and output vector, the approach is recognized to minimize an entirely new definition of frequency-based dynamic compliance. The method is applied to viscoelastic systems in plane strain conditions that are investigated by using the Arnold-Winther finite-element resorting to a generalized solid phenomenological model. Preliminary indications on how to address the actual manufacturability of the optimal specimen are eventually outlined.
