Course Name: ED3160 : Deformation & Failure of Engg Materials

Description: Introduction to failure in mechanical design and basic concepts of reliability; Structure of common engineering materials, their classification based on bonding, influence of structure on mechanical properties. Review of elasticity, plasticity (stress-strain curve, mathematical descriptions of elasticity and plasticity, yield criteria, constitutive properties), introduction to visco-elasticity (stress-strain response of polymers, frequency and temperature dependence, Maxwell and Voigt models, storage and loss moduli, time-temperature superposition), introduction to fracture mechanics (Griffith analysis, stress intensity factor, energy release rate, leak-before-break, cyclic crack growth) Fatigue (High-cycle vs. Low-cycle fatigue, different ways of estimating fatigue life, mean stress effects), creep (Mechanisms and common descriptions; primary, secondary and tertiary creep; creep rupture), design for surface integrity (Engineering models for wear, design guidelines for wear)
