Design of thermoelastic multi-material structures with graded interfaces using topology optimization
Abstract
A level set based shape and topology optimization framework is used to study the effect of graded interfaces in the optimization process of micro-architectured multi-materials. In contrast to previous studies interfaces are considered as smooth transition between phases instead of a sharp delimitation between two phases. A study on extreme thermoelastic properties of 2D isotropic composites is achieved and optimal design are presented. The study shows how taking into account smooth interfaces can influence the optimal design of these materials.
