    Abstract: The bonded joints in composite structures is a challenging point in both research study and industry application. Compared with homogeneous and isotropic material, there is higher chance of stress concentration and intrinsic weak for this anisotropic structures. It is most common source of failure in structural laminates. So it is important to mode... Show More

    Abstract: Two-phase flows are encountered in a wide range of industrial application. In the present work, two-phase computational fluid dynamics (CFD) calculations, using Eulerian–Eulerian model and commercial CFD package FLUENT 6.3, were employed to calculate pressure drops caused by abrupt flow area contraction in small circular pipes for two-phase flow of...

    Abstract: The theoretical and experimental investigation of the process of hydromechanical extrusion (HE) of aluminum alloys Al 5056 was carried out. The aim is to determine the optimal parameters of this process. These parameters were determined to minimize the extrusion force and damage factor of a workpiece by using explicit finite elements method. The re... Show More

    Abstract: The crane hook is fabricated with eight plates of 25 mm thickness and cut to the required size and dimensions as shown in the figure. The plates are riveted. Each crane hook carries 125 tones load. For this load the stress is found to be high and so high carbon steel with higher yield strength is suggested. After analyzing with different materials,...
