This course deals with fundamentals of mechanical behavior of broad class of materials. The primary focus is on the load bearing ability, types of loading and respective failure modes. The course also addresses mechanical properties sensitive as well as insensitive to the microstructure of the materials. The course attempts to capture the microstructure mechanical behavior correlations in materials.INTENDED AUDIENCE : Students undergoing any degree course in the branches of Metallurgical/Materials/Mechanical/Materials Science or its allied disciplineINDUSTRY SUPPORT : Automotive and metal forming industries
