摘要：

The pressurized thermal shock experiment NKS-3, of MPA Stuttgart (a large, cracked, hollow cylinder exposed to sudden cooling in presence of mechanical loads), is analyzed by means of a local approach of ductile fracture based on Rousselier damage model. This model can be calibrated by simple tests on cylindrical notched tension specimens. The crack growth is calculated from the stresses and the damage variable computed by a finite element program. The experimental and numerical results are in a good agreement. In parallel, a development of the model in the frame of ABAQUS finite element program has been described, using the Gurson formulation of the plastic potential which is very similar to the Rousselier formulation. © 1990.
