Response of fiber reinforced composites to underwater explosive loads
An in-house developed, verified and fully validated three-dimensional finite element code, with rate dependent damage evolution equations for anisotropic bodies, is used to numerically ascertain the damage developed in a fiber-reinforced composite due to shock loads representative of those produced by an underwater explosion. Three internal variables characterize damage due to fiber/matrix debo...
متن کاملInvestigation of Springback Angle in Single Point Incremental Forming Process on Explosive Welded Cu/St/Cu Multilaye
Nowadays, the role of light weight materials has grown up in important industries such as aerospace and biomechanics, but before the appliance, their strength should be increased. A modern way to increase this factor along with the lightweight factoris using bimetal sheets, hence, the design of multilayer sheets has been very much considered recently. In this study, explosive welded Cu/St/Cu mu...
متن کاملA Study on the Forming of Sheet Metal Parts Using Multi-Point Forming Technology
In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...
متن کاملSimulation and experimental work on manufacturing torispherical heads in explosive hydro-forming process
This study presents a numerical investigation on the deformation of the circular blanket against a male die under impulsive loading to form a torispherical heads shape. A finite element model was developed and verified with experimental tests for the explosive forming of the torispherical heads made of AA5083 aluminum alloy in the framework of LS-DYNA crash simulator software. The nature of the...
