Aims

On completion of this TLP package, you should:

• Have an appreciation of the mechanisms involved in creep deformation, and their general dependence on temperature and stress
• Understand what is meant by Primary, Secondary and Tertiary Creep
• Know how creep curves can be represented by (empirical) constitutive laws, and how the values of parameters in them, such as stress exponents and activation energies, can be obtained from experimental data
• Know how a conventional uniaxial creep test is carried out
• Be familiar with a particular set-up for experimental study of the creep characteristics of a material, available in wire form
• Understand the basics of Indentation Creep Plastometry
