"Hierarchical Modeling of the Mechanical Behavior of High Speed Steels as Layer-Structured Particulate MMCs";
Journal de Physique IV, 6 (1996), C6; S. 395 - 402.



Kurzfassung englisch:
High Speed Steels (HSS) produced by electro-slag remelting can be viewed as particle reinforced Metal Matrix Composites (MMCs) consisting of alternating layers of high and low inclusion volume fraction. These phase arrangements require specific models to be used in analytical and numerical studies of the elastoplastic response of HSS. In the present study, a hierarchical micro-meso-macro approach is discussed, which combines the Multi-Particle Effective Field Method (MEFM) for describing the matrix inclusion topology at the microscale with an extended lamination theory for handling the layered geometry at the mesoscale. In addition, a Finite Element based two-dimensional method is presented, in which HSS is modeled as a material with a graded microstructure. The obtained results are discussed in terms of overall elastoplastic behavior and of damage relevant microscale fields.
