Mechanical Behavior of Materials

3 units

A materials science based study of mechanical behavior of materials with emphasis on mechanical behavior as affected by processes taking place at the microscopic and/or atomic level. The response of solids to external or internal forces as influenced by inter atomic bonding, crystal/molecular structure, crystalline/non crystalline defects, and material microstructure will be studied. The similarities and differences in the response of different kinds of materials viz., metals and alloys, ceramics, polymers, and composites will be discussed. Topics covered include physical basis of elastic, visco elastic, and plastic deformation of solids; strengthening of crystalline materials; visco elastic deformation of polymers as influenced by molecular structure and morphology of amorphous, crystalline, and fibrous polymers; deformation and fracture of composite materials; mechanisms of creep, fracture and fatigue; high strain-rate deformation of crystalline materials; and deformation of non crystalline materials.
