• Proficiency in 1D structural calculations.
• Design and develop primary and secondary structures for rockets.
• Work with metallic and composite materials to optimize structural efficiency and weight reduction.
• Perform detailed CAD modeling of aerospace structures, ensuring integration with propulsion, avionics, and thermal systems.

2. Structural Analysis & Load Evaluation

• Conduct Finite Element Analysis (FEA) using tools like ANSYS, Abaqus to assess stress, strain, buckling, and fatigue life.
• Evaluate various loading conditions, including aerodynamic loads, inertial loads, dynamic loads, and thermal stresses.
• Perform hand calculations and classical structural analysis to validate FEA results.
• Conduct dynamic, thermo-structural, and Power Spectral Density (PSD) analysis for aerospace structures.

3. Failure Analysis & Safety Assessment

• Identify potential failure modes (yielding, buckling, fatigue, fracture) and develop mitigation strategies.
• Apply industry-standard failure criteria (e.g., Von Mises) for material selection and structural safety.
• Support design reviews, trade studies, and safety assessments to ensure compliance with aerospace standards.

4. Structural Optimization & Weight Reduction

• Apply topology optimization, lightweight material selection, and advanced manufacturing techniques to minimize weight without compromising strength.
• Explore alternative design configurations to enhance structural efficiency and manufacturability.

5. Manufacturing Support & Testing
