• Evaluate mechanical performance against structural limits, regulatory requirements and design and pressure vessel codes such as ASME BPVC and AWS D1.1.
• Apply NASA structural design and verification standards to ensure flight-class structural integrity, safety factors and analysis documentation.
• Assess component margins under mechanical, thermal and acoustic environments using static, model, vibration and explicit dynamic analyses.
• Document findings in clear, traceable reports and develop test requirements and plans to validate analytical results.
