With over two decades of structural FEA experience in the aerospace and advanced engineering sectors, I deliver high-fidelity numerical modeling, design validation, and lightweight optimization for mission-critical mechanical systems. Core Expertise: Static & Dynamic FEA: Linear/nonlinear stress analysis, fatigue life estimation, modal analysis, vibration, and multi-axial combined loading (bending, torsion, axial). Rotating Machinery & Shaft Design: Comprehensive evaluation of bearing stiffness, torque transients, dynamic start/stop response, and hydrodynamic/environmental interactions. Lightweight & Structural Optimization: Mass reduction strategies, cross-sectional tailoring, and material trade studies (high-strength alloys, corrosion-resistant metals, composites). Rigorous Analytical Validation: Every numerical simulation is cross-checked against classical hand calculations, beam/plate theories, and mesh convergence standards to ensure 100% dependable results. Workflow & Deliverables: Clear, publication-grade engineering reports detailing boundary conditions, mesh independence studies, stress/deflection contours, and practical design recommendations. Full transparency and reproducible simulation files. Flexible execution across commercial client environments (via remote desktop/floating licenses) or verified, commercially compliant open-source solvers (CalculiX, Code_Aster). Whether you need a quick second opinion on a failing component, baseline design verification, or a full end-to-end structural optimization report, I bring aerospace-grade rigor and engineering precision to your project.
