Intrinsic and statistical size effects in microforming

20th International ESAFORM Conference on Material Forming, ESAFORM 2017; Dublin City UniversityDublin; Ireland; 26 April 2017 through 28 April 2017This paper analyzes the intrinsic (grain size dependent) and the statistical (grain number and orientation distribution dependent) size effects of micron level polycrystalline metallic specimens under plastic deformation through a strain gradient crystal plasticity framework. The macroscopic and local behavior of specimens from very limited number of grains to high number of grains are studied and the results are discussed in detail taking into account different boundary conditions.Scientific and Technological Research Council of Turkey under the 3001 Programme (Grant No. 215M381
