Residual strains induced by drilling of glass-fibre reinforced polymers (GFRP) were determined using a hybrid experimental-numerical methodology. Experimentally, a set of GFRP specimens were drilled under well-defined tensile (calibration) stresses, using an especially designed tensile test device. To remove the effect of the initial residual stresses, this methodology considers differential stress values instead of absolute ones. Numerically, the experimental procedure was simulated using the finite element method. The induced drilling strains were determined by comparing the experimental measured strains with those calculated numerically. Clear differences between the selected drilling operations could be observed and evaluated.

“…However, for orthotropic materials such as fiber composites and wood the strain/stress relationship is not trigonometric. Residual stresses can still be evaluated, but in a more complex matrix format using seven calibration constants [38,39].…”

“…Furthermore these texture gradients might also lead to gradients in the elastic anisotropy. A series of investigations already discussed the determination of residual stress measurements on orthotropic and anisotropic materials using the hole drilling method [8,9], but the influence of gradients in the elastic properties has not been investigated yet.…”

Metal forming processes often involve large strain gradients which results in heterogeneous deformation and consequently residual stresses. Furthermore the strain gradients also generate variations in the deformation texture and related properties. For materials with a significant crystallographic elastic anisotropy such as ferritic steel, these textures may have a substantial effect on the reliability of the determination of residual stresses. In the present investigation this influence is examined for the hole drilling method by a combination of experiments and finite element simulations.
