Sheet metal is widely used in industry and different production processes. The present work aims to reduce the bending force air-die process. Different mild steel sheet thicknesses (0.5, 0.75, 1, 1.25 mm) were considered, two techniques proposed. first technique involves an annealing process, while second one considers cutting a rectangular hole along line. stress was calculated using Autodesk ...

Drawing of square section rod from round bar can be done with two die shapes. In the first die shape, deformation starts from corners of the square and in second die shape, deformation starts from sides of square. This article has compared the drawing force for both die shapes and as a result optimum die shape was determined. Due to complexity of metal flow inside the die, analyzing of actual p...

Although, there has been a dramatic improvement in the ability to therapeutically alter the course of this malignancy, a substantial proportion of patients may either not respond to treatment or experience relapse and eventually die of progressive disease that is not sensitive to further chemotherapy [1] underscoring the need of more accurate methods of prospectively identifying patients with d...

Satin SiCf/SiC composite has a wide range of applications; it is necessary to study its mechanical properties. The progressive failure five-harness five-layer satin weave plate composites was explored experimentally and numerically in this research. bending properties were derived elucidated at ambient temperature through three-point experiment. generation progression damage observed by CCD cam...

This paper presents a new framework for recovering superquadrics with global deformations from multi-view real range data. The framework aims at improving confidence and accuracy of recovered models by utilizing multiview information, and consists of the initial superquadric model recovery, view registration, view integration, and final model recovery from integrated data. A quadrant analysis t...

-A detailed study of conditions leading to fiber fracture during the consolidation of Ti-14wt %A~21 wt%Nb/SiC (SCS-6) composite monotapes has been conducted. For this continuous fiber reinforced composite system, the incidence of fracture increases with consolidation rate at higher process temperatures. Increasing consolidation temperature at a fixed pressure reduces the number of breaks per un...

During tube hydroforming process, the friction conditions between and die have a great importance on material plastic flow distribution of residual stresses final component. Indeed, three-dimensional finite element model process in case square section has been performed, using dynamic static approaches, to study effect both induced by process. First, comparative numerical experimental results c...
