Composites are a useful type of material due to their ability to be created for specific applications. On the other hand composites often leads to a challenging optimization problem. Since composites often consists of more than two constituent materials it can be challenging to distribute the constituent materials in order to fulfill a certain mechanical property. The goal of this report is to construct an algorithm to optimize mechanical properties for a composite. The geometry of the composite is a 2-dimensional square with a pre-crack. The mechanical properties that the algoritm seeks to optimize is toughness and minimized stress in the crack tip. The results shows that the algoritm can be used in order to redistribute the constituent materials in order to improve a mechanical property.
