PLANE STRAIN CREEP AND PLASTIC DEFORMATION ANALYSIS OF A COMPOSITE TUBE.

Abstract A method of analysis and associated computer program is described for the generalized plane strain analysis of transient creep and plastic deformations of composite cylinders. The material properties are permitted to vary with temperature and the axisymmetric loading conditions may vary with time. The loading may include any combination of internal pressure, external pressure, axial load and radial variation of thermal strains. Several forms of creep law are permitted including an iso-curve plastic strain law for use in obtaining certain plasticity solutions from the creep solutions.
