Progress of Continuum Damage Mechanics

抄録

The notion of, and the progress of continuum damage mechanics along with the microscopic aspects of material damage are reviewed. Starting from a brief review of material damage and the notion of continumm damage mechanics, mechanical modelling of the damage states and the damage variables used to describe them are discussed. Then, the extension of the classical creep damage theory to the anisotropic state of creep damage and the problems of elastic-plastic damage are discussed. Besides the application of these damage theories to the damage of metals, concrete and rocks, recent works on spall damage, fatigue damage and creep-fatigue damage are reviewed. The applicability of continuum damage mechanics to the analysis of boundary value problems, and the local approach to fracture problems by means of continuum damage mechanics are also referred to.
