Samenvatting

Microstructural damage evolution is reported to influence significantly the failures of new high-strength alloys. Its accurate quantification is, therefore, critical for (1) microstructure optimization and (2) continuum damage models to predict failures of these materials. As existing methodologies do not fulfill the requirements, there is an active search for an accurate damage quantification methodology. In this article, a new, micropillar, compression-based methodology is presented, whereby damage evolution can be quantified successfully through the degradation of the modulus caused by previous deformation.
