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
  • Economical and faster product development by cutting prototype developments and expensive testing
  • Detailed failure mode and effect analysis can be carried out to study failed designs
  • Can be used at any phase in the product life cycle to pinpoint anomalies and establish performances
  • Provides a platform to continuously upgrade and develop an optimum product
  • Can be interfaced with optimization and probabilistic design algorithms to generate a robust design problem statement
  • Procedures Used to Analyze Engineering Structures
  • Acoustic Analysis
  • Coupled Fluid-Structure Analysis
  • Coupled Thermal-Structural System Analysis
  • Thermal (Heat Transfer) Analysis
