Evaluating Residual Stresses Induced by Drilling of Ti-6Al-4V Alloy by Using an Experimental-Numerical Methodology
Communication avec acte
An experimental-numerical methodology is applied to evaluate the residual stresses induced by drilling of Ti-6Al-4V alloy. The influence of ultra-high cutting speeds on the residual stress distribution is analysed. These ultra-high cutting speeds are produced by a turbine system powered by compressed air, which are commonly used in the hole-drilling equipment for residual stress measurements. The applied hybrid methodology has demonstrated an important role on the optimization of the drilling operations parameters for an improved residual stress distribution.

Article dans une revue avec comité de lectureNOBRE, Joao Paulo; STIFFEL, J.-H.; NAU, A.; OUTEIRO, José; BATISTA, Antonio; VAN PAEPEGEM, W.; SCHOLTES, B. (Elsevier, 2013)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 ...

On the selection of Johnson-Cook constitutive model parameters for Ti-6Al-4V using three types of numerical models of orthogonal cutting Communication avec acteZHANG, Yancheng; OUTEIRO, José; MABROUKI, Tarek (Elsevier, 2015)Johnson-Cook constitutive model is still the most used model in metal cutting simulation, although several drawbacks reported in the literature. A high number of Johnson-Cook model parameters can be found in the literature ...
