✦ Synopsis

We construct a three-dimensional theory of a material in which damage may occur in creep. In the one-dimensional case the differential equations are simple enough so that they may be studied exactly, but complicated enough to exhibit a variety of interesting phenomena. Solutions are found to be homogeneous damage fields, coexistent homogeneous damage fields separated by singular surfaces, an homogeneous undamaged body with a smooth transition into a damaged region in the interior, which may be interpreted as a shear band, and periodic solutions with transitions between damaged and undamaged regions.

## A cumulative damage theory is developed based on the concept of bounds on residual life. Previous results applicable to fatigue are generalized to creep-rupture and to creepfatigue interaction. By defining a creep endurance limit and void-initiation life fractions, a complete symmetry is establ
