Blast and Impact Resistant Structures
Prof. Hrishikesh Sharma · IIT Guwahati
About
The course "Blast and Impact Resistant Structures" offers an in-depth exploration of the behavior of structures subjected to extreme events such as blasts and impacts. Students will gain an understanding of key concepts such as quasi-static approximations, stress waves, and energy-absorbing systems. The course covers the dynamic response of structural elements under blast loading, with a focus on single-degree-of-freedom (SDOF) and multi-degree-of-freedom (MDOF) analysis methods. Additionally, students will learn about pressure-impulse diagrams, dynamic buckling, and failure mechanisms, equipping them with the skills to design structures capable of withstanding severe dynamic loads.
Intended audience: Btech, Mtech, PhD students
Prerequisites: Structural Dynamics
