FINITE ELEMENT ANALYSIS

Weaver Engineering uses FEA as a tool to assist in design for strength, fatigue resistance, stiffness, stability, impact, or resonance. We can build a FEA model from most likely forms of geometry definition: Drawings, datasets (iges, dwg, dxf, prt -Pro Engineer, sat -ACIS, parasolid - Solid Works), physical samples, or sketches.

We use Cosmos/m for finite element analysis of problems involving static, transient and steady state mechanical dynamic and heat problems, general contact, and non-linear problems. We have a wide variety of in-house tools for post calculations such as rainflow analysis, other damage predictors, and weld analysis .

FEA Samples
Below are samples from some of the modeling that we haveperformed:
