Creep Continuum Damage Mechanics—Studies of Size Effects and Weldments
The paper summarizes the development of constitutive equations for creep Continuum Damage Mechanics, CDM, in metals; and solution methods are discussed for notched and cracked specimens which are identical in geometry, but different in size; and, for weldments which include three material zones. In both cases it is shown that, to achieve accurate predictions, it is essential to use constitutive equations, which accurately reflect the underlying physics of the dominant processes.
