Micromechanical modelling of strain path dependency in FCC metals

摘要: The analysis of the formability metals is a traditional topic in mechanical engineering, which still characterised by many open issues. In spite decades research, this field continues to trigger new challenges, especially promoted industrial progress. growing need for more precision forming processes and exploitation complex manufacturing processes, necessitates better understanding relevant micromechanical development sophisticated engineering tools. physical origins deformation behaviour observed metals, reside, among others, textural anisotropy material dislocation structures accompanying plastic deformation. microscopic mechanisms, associated with presence these microstructural entities, affect macroscopical metal, altering its formability. This thesis addresses two major aspects both based on underlying evolving microstructure: (1) prediction limits (2) strain path change effects. following sections shortly highlight challenges fields, from research scope has been derived
