Abstract

The EPRI procedure for evaluation of elastic-plastic fracture mechanics parameters has been described. Using an analogy of visco-plastic problem with a described procedure, the possibility of application of EPRI procedure to the stacionary creep problems has been analysed. Two examples of application of such a procedure have been presented, both for cylindrical pipes at high temperature, one under internal pressure, and the other one loaded by axial forces. Pipe under internal pressure was used for the C* integral evaluation.

Keywords: C* integral, EPRI procedure, visco-plastic behaviour, high-temperature components
