Finite Element Analysis

Finite Element Analysis (FEA) is a numerical method used to solve a mathematical model of a structure or system. FEA predicts the response of a structure (e.g., automotive bushing, O-ring, seal) to applied forces, temperatures and vibrations. The inputs to the model are the material properties, geometry and ambient conditions.

The stress-strain properties of polymeric and elastomeric materials are nonlinear and highly temperature dependent. The complexity in carrying out FEA is further compounded by the presence of viscoelastic characteristics and geometry dependent deformations.

In many engineering applications, analytical solutions may not be possible, and FEA may be the only practical way to analyze the design.

Benefits of Finite Element Analysis

• Can be incorporated during the design phase to select the best design for a given application
