About the Seminar:

This is an academic PhD research seminar presented by a doctoral candidate at IIT Delhi’s Department of Applied Mechanics.

“Wave Propagation and Damage Evolution in Heterogeneous Layered Media under Impact Loading” — indicates the research focuses on how mechanical waves travel through layered, non-uniform materials and how damage (such as cracks or material breakdown) initiates and grows when such materials are subjected to impact forces.

Layered heterogeneous media are materials composed of different layers with varying properties (such as composites or geological strata), which behave differently when stressed, especially under high-speed impacts. The study of wave propagation in such media is critical for predicting structural response and damage progression.

Topics likely covered in the seminar include:

Dynamic response of materials under impact (how stress waves travel and reflect through layers).

Mechanisms of damage initiation and evolution, including crack formation and growth in layered structures.

Analytical, computational, and possibly experimental approaches to model and understand such complex behaviour.

The research has applications in structural engineering, defense, materials science, and impact-resistant design, where understanding dynamic damage mechanisms is essential.
