SimDes Partner offers not only FEA verification of products with a simple answer yes/no on whether a design is meeting all structural requirements. In addition to general recommendations and guidance on how to improve design performance, SimDes Partner also deliver comprehensive structural design optimisation services. Depending on the design stage we can conduct sizing, shape and topology optimisation.
Sizing optimisation is applicable for components with fixed shape and topology. This type of optimisation is widely done on laminate composites structures for fibre directions and layer thickness optimisations. Topology optimisation is one of the most popular due to the simple formulation of topology optimisation problems. An optimal material distribution can be determined for problems with specific objective definitions within an allowable design space and constraints. These general approaches offer the possibility to minimise the used material and therefore reduce structure weight significantly. The goal of shape optimisation is to change the shape of a structure such that the optimisation problem is solved in the best possible way. Minimising weight, maximising stiffness, modification of eigen-frequencies or minimising stress are the most common shape optimisation goals. A special class of shape optimisation, Topography Optimisation, is often used in sheet metal part design.
