A topological hierarchy-based approach to layered manufacturing of functionally graded multi-material objects

A topological hierarchy-based approach to layered manufacturing of functionally graded multi-material objects

This paper presents an approach based on topological hierarchy to representation and subsequent fabrication of functionally graded multi-material (FGM) objects by layered manufacturing. The approach represents an FGM object by material control functions and discretisation of slice contours. Based on the topological hierarchy of slice contours, material control functions are associated with cont...

A Decomposition-Based Approach to Layered Manufacturing

An isogeometric approach to topology optimization of multi- material and functionally graded structures

Alireza H. Taheri, Krishnan Suresh* Department of Mechanical Engineering, UW-Madison, Madison, Wisconsin 53706, USA. * Corresponding author, email: [email protected] Abstract A new isogeometric density based approach for the topology optimization of multi-material structures is presented. In this method, the density fields of multiple material phases are represented using the isogeometric NURBS-...

Vademecum-based approach to multi-scale topological material design

The work deals on computational design of structural materials by resorting to computational homogenization and topological optimization techniques. The goal is then to minimize the structural (macro-scale) compliance by appropriately designing the material distribution (microstructure) at a lower scale (micro-scale), which, in turn, rules the mechanical properties of the material. The specific...
