Design Validation

Validation of designs using Finite Element Analysis (FEA) is one of the core functions in design cycle.

Butler has vast experience at validating design. This includes:

• Stress validation for margin of safety and component sizing
• Component Layout validation to verify offset and loft surfaces or interface points (through various methods)
• Engineering design check with tolerance stack-up analysis, drafting review, GD&T, assembly check, interference validation
• Internal reviews to check deliverables against engineering requirements

Butler provides value to customers through the use of FEA, including:

• Simulation of real-life situations
• Prediction of services life
• Vibration prediction and prevention
• Correlation to test results
• Optimization based on shape, sensitivity, fatigue and fracture analysis and kinematic analysis

Butler's experience in using software tools like Ansys, Nastran, Abaqus, Hypermesh, Patran, etc. to the fullest potential ensures that we deliver the highest-quality services in response to clients' diverse requirements.
