Effect of crystal orientation on indentation-induced residual stress field: simulation and experimental validation

Numerical results related to the study "Effect of crystal orientation on indentation-induced residual stress field: simulation and experimental validation". Experimental determination of local residual stress fields beneath a spherical indent on a copper single crystal revealed the presence of a significant tensile residual stress zone. This finding was adequately reproduced by Crystal Plasticity Finite Element simulations. Further simulations of one spherical indent on many other crystal orientations showed a strong variation of the residual stress field with crystal orientation. Accumulative effects of five superposing indents were simulated on two extreme orientations and . The simulations showed that plastic anisotropy is responsible for potentially uneven compressive residual stresses after surface mechanical treatments
