Experimental investigations on the austenitic stainless steel X6CrNiNb18-10 (AISI – 347) and concomitant atomistic simulations of a FeNi nanocrystalline model system have been performed in order to understand the basic mechanisms of fatigue damage

As part of an existing research project [1] the fatigue behaviour at room temperature of the austenitic steel X6CrNiNb18–10 was investigated. From a combination of interrupted low cycle fatigue tests and EBSD-measurements in the scanning electron m

To investigate the effect of model thickness on simulated strain and stress fields in two-phase materials three-dimensional and two-dimensional finite element simulations were performed. The microstructure of the models was generated both by a stocha

In this study, the local deformation of an Al-7wt.% Si alloy, a 10 vol.% particle reinforced and 20 vol% short fibre reinforced metal matrix composites is studied. The strain field at the surface of the materials during tensile testing inside a scann

A problem of the applicability of two-dimensional models in simulations of heterogeneous material behavior on the meso-scale level has been studied, using a metal matrix composite (MMC) structure as an example. In order to incorporate explicitly the

In particle reinforced metal matrix composites (MMCs) such as Al/SiCp, there exist microscopic inhomogeneities due to the different elastic–plastic behaviour of the phases. As a result, stress and strain concentrations emerge at these inhomogeneiti

In this contribution, a mesomechanical approach to simulate the mechanical behavior with explicit consideration of the three-dimensional structure is applied to study the elasto-plastic response of a metal matrix composite material under tension. A p

Steels are subjected to various atmospheres which can affect their strength, deformation and damage behaviour at room temperature as well as at increased temperature. These alterations are due to micromechanical effects which will influence the dislo
