In this paper, a new method for fracture analysis of notched cylindrical cases under explosive loading of High Explosive internal charge has been presented to determine fracture time, fracture radius, fragment velocity and acceleration. Also the fracture dynamics has been simulated by explicit and nonlinear LS-DYNA code. In numerical simulation the behaviour of metallic case has been modeled by...

Abstract In this paper, the constitutive equation parameters (Johnson–Cook parameters) of 33MnCrB5 material were determined with help tensile tests. Initially, Johnson–Cook (JC) model was used for performing simulations sample finite element analysis ANSYS software. For these operations, first at a certain temperature (24 °C) and low strain rates (10 −1 , 10 −2 −3 s ) quasi-static tests perform...

Temperature Analysis of Friction Stir Welding (AA6061-T6) with Coupled Eulerian-Lagrangian Approach.
Abstract For Friction Stir Welding (FSW), several simplified FEM models have been developed to explain key parts of thermal-mechanical phenomena. In this study, simulate the FSW process AA6061-T6 aluminum alloy, a thermo-mechanical 3-D finite element model based on Coupled Eulerian-Lagrangian (CEL) approach is used. The CEL method combines benefits both Lagrangian and Eulerian approaches, allow...
On a Gleeble-3800 simulator, isothermal hot compression tests of an as-cast N06625 nickel-based alloy were conducted in wide range temperatures (950–1200 °C) and strain rates (0.1–50 s–1). Considering the influence friction adiabatic heating test, flow curves corrected. A modified Johnson-Cook, strain-compensated Arrhenius-type Hensel-Spittel constitutive models established based on corrected c...
