Size Effects in Cosserat Crystal Plasticity,of a simple onedimensional shear test involving one single slip system and vanishing microrotation prescribed at the boundaries of a material strip of width 2.. The inhomogeneous distribution of slip in the channel mimics the piling-up of dislocations against the boundaries. The free energy density

,On the Influence of POIsson’s Ratio on Phase Transformations Limiting Surfaces,ationships defining the limiting surfaces in the case of auxetic phases are derived and the difference with the case of positive Poisson’s ratio is highlighted. Limiting surfaces for phase transformations in the cases if one or both phases are auxetic materials are compared with the limiting surface

Geometrically Nonlinear Cosserat Elasticity with Chiral Effects Based upon Granular Micromechanics,es when we consider the granular microstructure inherent in all matter. The discussed discrete-continuum identification, that follows Piola’s ., is utilized to develop kinematic measures in the framework of finite deformations. These kinematic measures are then utilized to express the internal defor

A Technique for Determining True Deformation Diagrams Under Dynamic Tension Using DIC,dern means of registration of parameters of dynamic processes are applied. The results of approbation are given on the example of dynamic tests of samples of sheet steel 09G2S. The technical and true strain diagrams in the static and dynamic range of strain rates are determined.
