Finite Element Analysis

An essential CAE tool for new product design and development

We are experts in the application of finite element analysis software to analyse complex structural load cases.

The numerical models that we create are, by definition, simplified representations of a physical design and its environment (load conditions). Load cases are derived from design targets and successful use of finite element analysis starts with a thorough interpretation of the design targets to identify the most appropriate modelling technique at each stage of the design process from concept generation to final certification. The models enable a detailed prediction of the performance characteristics of a design before it is actually built which means that the performance of the final design can be engineered to be right first time, eliminating the need for expensive prototypes.

This predictive analysis capability is performed using multi-core licences of the industry standard codes provided by the software companies Altair (HyperWorks) and LSTC (LS-DYNA3D). These codes and the associated pre and post-processing software packages enable us to represent a wide range of linear and non-linear load cases. They both have an extensive library of material models to capture material response during loading for a wide range of strain rates and advanced contact interfaces to allow for complex interaction of parts.

Explicit non-linear solvers such as RADIOSS and LS-DYNA3D allow fluid-structure interaction using ALE and SPH techniques. These formulations are particularly useful for solving high speed load cases such as bird strikes on airframes or the sloshing of fuel within an automotive fuel tank during crash test.
