Ørts TI - Fatigue Damage Development in a Steel Based MMC T2 - Computer Modeling in Engineering \& Sciences PY - 2000 VL - 1 IS - 2 SN - 1526-1506 AB - The development of fatigue damage in a tool-steel metal matrix discontinuously reinforced with TiC particulates is analysed using a numerical cell model. The material is subjected to cyclic loading, and the matrix material is represented by a cyclic plasticity model, which uses a superposition of kinematic and isotropic hardening, with continuum damage mechanics incorporated to model fatigue damage evolution. The cell model represents a material with transversely staggered particulates. With focus on low cycle fatigue, the effect of balanced as well as unbalanced cyclic loading is studied.
