Finite Element Analysis (FEA)

FEA is a traditional engineering technique for predicting the responses of structures and materials to applied loads such as force, temperature, vibration and displacements.   Typical outputs from FEA analysis include quantitative estimates of displacements, stresses, strains etc in the analyzed structure. These outputs when coupled with failure models can provide invaluable product reliability insights.   Before committing to the expense and schedule impact of physical prototyping, entire designs can be modeled and evaluated for performance to specification, analyzed for failure points, failure modes corrected and reliability improved.

Failure analysis is performed at a component level (discrete devices, cable assembles), up through PCBAs, sub assemblies, and complete (entire) products.

Benefits include:

  • Reduced development time and costs of new products
  • Product reliability insights
  • Quality improvements
  • Reduced development time and costs of new products: before committing to the time and expense of physical prototyping, the design can be modeled and evaluated for performance, failure points identified, and failure modes corrected
  • Quantify critical parameters such as stress/strain at failure sites of interest
  • Explore and quantify "what if" design scenarios - understand / predict the impact of changing materials, varying geometries
  • Simulate test conditions such as temperature cycling, drop, vibration and fatigue life tests
  • Provide inputs for product useful life assessment
