Industry relevance

This module fundamentally focusses on various aspects of engineering design namely, design process, design space, material selection, loads, obvious and unobvious failure modes hence stress and vibration margin and basic lifing practices in great detail. Enough discussion is provided to physics of vibration to bring about clarity for young engineers. Wherever relevant technological aspects of product lines are also discussed.

The module also addresses the modern best practices such as sensitivity analysis, probabilistic design, reliability assessment and basic introduction to digital twin technology.
Module incepts with interviewer’s expectations that sets the ideal direction of discussion of design
A special module is included to give fundamental literacy in composite mechanics.
