Mechanical Behaviour of Materials (Part - II)

Prof. Shashank Shekhar and Prof. Sudhanshu Shekhar Singh · IIT Kanpur

Start with lecture 1 At NPTEL

About

This course has a vast syllabus and hence it has been partitioned into two sections. At the end of both the sections of the course, students should be well conversant with theory of plasticity, theory of dislocations and its relation to various mechanical properties exhibited by various materials, viz. strength, fracture, fatigue and creep.

Intended audience: Undergraduate Students and first year graduate students of following discipline: Materials Engineering, Mechanical Engineering, Metallurgical Engineering, Aerospace Engineering

Prerequisites: A course related to nature and properties of materials
