Finite Element Analysis
Spires offers over 30 years of combined experience in Research and Development, Structural design, Finite Element Analysis (FEA) and Academic and Industrial Consultancy. Our skills set includes amonst others UNIX, Linux and the Windows operating systems; Programming languages like C, VB, Python, Matlab and Maple and most industry recognised CAD packages. Our engineeers are conversant with the rigid body simulation tool, Matlab-Simulink, and are able to utilise a range of meshing tools: ABAQUS, PATRAN, Hypermesh and Simlab to name a few. FEA makes possible the prediction of how a certain design will measure up against specifications even before a prototype is built, allowing quick improvements to the design if necessary. Packages we use include:
• FE LS-Dyna , ABAQUS, NASTRAN, FEMAP, Ansys and IDEAS
• Fatigue analysis tools: FE-Safe
• Optimization tools: Optistruct, Hyperstudy
• Statistical analysis tools : Nessus and Minitab
Examples of the work we do are listed below by industry
