Abstract
X-ray diffraction (XRD) and the finite element technique (FET) to measure the residual stresses (RS) inside Al1060 rods produced by forming operation at three different half extrusion angles (HEA = 20°, 40°, and 60°) were applied. The results of the experimental work and FET illustrate a good convergence in terms of the relationship between extrusion force and displacement with an error ratio reaching 15 %. The effect of HEA = 20° on extrusion force is the lowest compared to others. Moreover, the behavior of the obtained residual stresses from XRD and FET is in good agreement with the existence of some variation in their values. The profile of these stresses is in a tensile state near the rod surface and a compressive state near the axis at HEA = 20° and 40°. In contrast, compressive residual stresses are obtained close to the surface and center of the extruded rod at HEA = 60°.
期刊介绍：
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
