Ratcheting Behavior and Ratcheting-Fatigue Interaction of Engineering Materials
Abstract: In this presentation, macroscopic experimental observations for the ratcheting behavior and ratcheting-fatigue interaction of some engineering materials are introduced rst, and then some corresponding cyclic constitutive models constructed in the framework of phenomenological visco-plasticity at innitesimal strain are outlined. Finally, some topics necessary to be studied in the future are provided. The outline of the presentation is:
I) Ratcheting Behavior of Metal Materials
Uniaxial and multiaxial ratcheting;
Cyclic visco-plastic constitutive model for multiaxial ratcheting;
Constitutive models for time-dependent ratcheting;
II) Ratcheting-Fatigue Interaction
Damage-coupled cyclic constitutive model for ratcheting-fatigue interaction
III) Discussion on Future Topics
The seminar takes place at 3:00 p.m. in the ICAMS seminar room UHW 11/1102, Stiepeler Straße 129, 44801 Bochum.
