FEA of Composite Structures

Application domain

As “engineered materials”, composites offer product manufacturers several advantages in terms of weight and performance, however they also come with several challenges in terms of product design. Delamination and fatigue failure, micro-cracking leading to eventual failure, and other mechanisms that aren’t a factor in designing with metals are very important for composites. They are also not well understood, and because of long and expensive manufacturing processes, physical prototyping is even less practical. Without the right CAE tools, selection of appropriate material can be both time and resource consuming.
Hexagon’s (MSC Software) extensive solution capabilities in composites help our customer in analyzing and enhancing their designs. The tools offered by Hexagon (MSC Software) are ideal for any of the common types of composites, namely, polymer matrix, metal matrix, ceramic matrix, carbon matrix composites and more.
