description

Composite materials are engineered materials made from two or more constituent materials with significantly different physical properties. In a typical configuration, (hard) filler particles are surrounded by a matrix of a second material which binds the filler particles together. Because the characteristics and relative volumes of both the matrix material and the various filler particles can be manipulated, these materials show an almost infinite range of physical properties. The aim of this project is to develop efficient numerical methods for the simulation of material responses. In addition, the analysis of the corresponding discrete models shall lead to a better understanding of how composites behave and how certain properties depend on the controllable variables. Both simulation and analysis provide the opportunity to develop materials with enhanced performance for the particular industrial applications.
