- Introduction: Primary and secondary creep. Stress dependence of creep, Temperature dependence of creep and Time dependence of creep. Mode of creep deformation. Dislocation glide and Dislocation climb. Role of grain boundaries during creep deformation.
- Creep Theories: Relative creep strengths of engineering materials. Creep under variable stress and temperature conditions, mechanical equations of state.
- Application to Design Problems: Creep under complex stress loading equivalent stress and strain criteria; application to practical problems.
