Finite Element Analysis Skill

Purpose

Provide expert finite element analysis capabilities for aerospace structural analysis including static stress, buckling, and dynamic response.

Capabilities

• NASTRAN, ABAQUS, ANSYS model setup
• Mesh generation and quality metrics
• Element type selection and justification
• Load case definition and combination
• Boundary condition specification
• Static stress analysis execution
• Buckling and stability analysis
• Results post-processing and margin calculation

Usage Guidelines

• Select appropriate element types based on structural geometry and loading
• Verify mesh quality metrics meet aerospace standards
• Apply proper load factors per certification requirements
• Use correct material allowables for temperature and environment
• Calculate margins of safety using appropriate failure criteria
• Document all modeling assumptions and simplifications

Dependencies

• MSC NASTRAN
• ABAQUS
• ANSYS
• HyperMesh
• Femap
