Finite Element (FE) simulation of sheet/tube forming precision depends mainly on the accuracy constitutive modeling. The present paper aim is to compare models fit stress-strain curves. accurate deformation behavior SS 304 tubes modeling hardening behavior. Deformation data tensile specimens cut from tubular sample were collected by conducting Uniaxial tests (UTT) at three different rolling dir...

Based on the actual parameters of capacitor energy storage cabinet top monorail train, built cabinet’s finite element model. Then, according to EN 12663-1, set calibration conditions and fatigue working conditions. Carried out simulation calculation under different conditions, respectively. The results static show that maximum equivalent stress each node model is smaller than allowable all Ther...

We discuss the concept of a glass transition line in the temperature-shear-stress plane in the context of recent simulation data for a metallic melt and dense-packed granular systems. Analyzing these data within a schematic model of the mode-coupling theory for dense glass formers under shear, values for the critical dynamic yield stress (the stress resulting in the limit of arbitrarily slow sh...

In hot forming process, the workpiece undergoes plastic deformation at high temperature and the microstructure of the workpiece changes according to the plastic deformation. These changes affect the mechanical properties of workpiece. In order to optimize this process, both the plastic deformation of workpiece and its microstructural changes should be taken into consideration. Since material be...

This study was performed to analyze the forming fracture of crash box with extruded Al6060-T6 profile. Deep drawing test evaluate formability For various specimens, deep tests were repeated measure maximum stroke at which did not occur. The finite element analysis for calculate principal strain through obtained stroke. limit diagram design concave shape calculated strains FEA. optimized by usin...
