Description
Optimierung eines Konzeptes zur Modeliierung des Kriech- bzw. Schädigungsverhaltens von Bauteilen au
FKM 2000
Issue number 249
Project no. 218
Abstract:
The aim of this research project was to further improve and optimize the modeling of the creep behavior of high-temperature CrMoV steels in the damage phase (tertiary creep) carried out in the predecessor project A75. A description of the creep behavior including damage that is as realistic as possible is necessary for calculating deformations, stresses and damage in components under long-term loading. This allows conclusions to be drawn about the expected remaining service life. For this purpose, the representation of the interaction between deformation and pore damage was generalized. Based on these considerations, an improved model was created and verified which, in addition to the use of an anisotropic pore damage parameter (tensor), is characterized by the possibility of dropping the restriction to strain-limited pore growth.
