Very High Cycle Fatigue (VHCF) using ultrasonic machines is a subject that receiving growing attention. Recent developments focus on biaxial stresses which are of interest to industries such as the aeronautical where plane appear in fuselage and wings. It has been shown before in-plane cruciform specimens can be changed so different biaxiality ratios achieved from equibiaxial pure shear. This p...

Dissimilar friction stir welding joints are widely employed in the industrial field due to excellent microstructural and mechanical properties of resulting joints. Nevertheless, further enhance weld properties, addition reinforcement particles on joint-line during process has been proven effective for increasing its performance. In present investigation, microstructure impact behaviour FSWed be...

Friction stir welding has become important in many areas of production and is increasingly used for joining aluminum components. For long seams, conventional tools with only one pin reach their technical limitations due to low gap bridgeability. When aluminum, the stirred surface layers, such as oxides, lead a decrease static dynamic strength since linear accumulations are formed seam. The aim ...

Abstract The shape of the projectile seems to determine effect a ballistic impact and failure mechanism. In this study, numerical analysis with different shapes, i.e ., ogive, blunt, conical, hemispherical is performed. target circular sandwich plate an outer diameter 315 mm, which composed three layers thickness 1 mm for each layer. These will be filled materials such as 1100-H12 aluminum allo...
