Description

To make students fully familiar with,(i) Dynamic, Impact and Impulsive load(ii) The deformation and failure mechanism of materials and structural components.(iii) The design principles and guidelines of structural and machine components.

Learning Outcomes

1. 1. Demonstrate indepth understanding of the concepts of dynamic, impact and impulsive loads and explain the resulting stress-strain properties influenced by strain rate.
2. 2. Explain deformation and failure mechanisms of engineering materials and components/systems under impact and impulsive load.
3. 3. Analytically predict the deformation and failure modes under impact and impulsive load and validate through experimentation.
