In this study, a novel approach for residual stress (RS) distribution on forged AA7175 is considered to replace and simplify the manufacturing process, based on the lean manufacturing concept. AA7175 alloy is a quench-sensitive material applied in the aeronautics industry, which is subjected to vibration and cyclic loads leading to fatigue failure....
The benefits of laser welding include higher production values, deeper penetration, higher welding speeds, adaptability, and higher power density. These characteristics make laser welding a superior process. Many industries are aware of the benefits of switching to lasers. For example, metal-joining is migrating to modern industrial laser technolog...
Residual stresses on aluminum parts can be modified during heat treatments. During solution heat treatment, quenching, and aging, metallurgical transformations combined with thermal gradients lead to a modification of parts properties. Quench and aging treatments sensitivity of AA 7175 aluminum alloy components is addressed in this work. Samples ha...
Challenging problems of computational mechanics may often be characterized by large deformations that are common in manufacturing processes such as forging. The finite element method faces difficulties in simulating large deformations, due to severe mesh distortion. A solution to overcome these difficulties is to use meshless methods like Smoothed...
Shot peening is widely used in automotive and aeronautic industries to improve fatigue life of metallic components. Its beneficial effects are mainly due to the residual stress field caused by the plastic deformation of the near-surface region resulting from multiple shot impacts. It is therefore important to know the values of the induced residual...
