Quarter model of a tank restraint which failed during fatigue testing as a FEA done by different consultants didn’t highlight the design problem. The analysis resulted in recommendations on a completely different design concept, which then proved to withstand the intended loads.
Simulation of a weld overlay repair of a big process vessel. The cooling and shrinkage of the weld filler material causes stresses and deformations. The analysis resulted in recommendations on how to improve the location and sizes of the weld patches to minimise distortion.
Stress analysis of cradle with payload subjected to transport accelerations. FEA model includes a detailed representation of the lashings used to strap the payload to the cradle, and the tie-down of the cradle to the aircraft. Report identified weaknesses and provided recommendations for improvement.
