Design and analysis

 Executing non-conformance disposition.
 Performing GD and T tolerance stack-up analyses to assess the assembly interface impact.
 Calculating the stress concentration (Kt) using Peterson chart for different geometric features.
 Performing fatigue (LCF: strain-based approach)/fracture mechanics (LEFM and EPFM based on K-field analysis and J-integral
formulations) assessment to ensure continued airworthiness.
 Rotor overspeed assessment using Hallinan equation and imbalance check.
 Back-to-back analysis and analytical correlation/validation using ANSYS APDL.
 Surface and Solid Meshing using hyper mesh.
 Performing design studies to introduce new repair schemes and dimensional restoration initiatives.
 Applying engineering judgement and hand calculations to assess structural integrity and functional impact of deviations.
 Preparing Design Record Books (DRB) documenting substantiation.
Tools used – Catia, Siemens NX, Siesta, Ansys classic (APDL), Altair hyper mesh
