Taylor anvil test is one of the dynamic method in which we can determine dependences strain, strain rate, temperature on flow stress. With this method, each cross sec-tion or along axial section specimen conditions under different states stress, rates and subsequent changes microstructure material. This paper describes experimental results (TAT) for TRISTAL carbon steel. The experiment was perf...

Abstract The authors introduce an experimental-analytical method for determining the average temperature values in PSZ (primary shear zone) and SSZ (secondary during orthogonal turning of grade 2 titanium with a use uncoated carbide tool positive rake angle flat face. presented is based on algorithm which stress are calculated by means Johnson–Cook constitutive equation Oxley’s model cutting me...

The simulation of material machining using finite element models is a powerful tool for the optimization simulated processes and tools, as well determination cutting process characteristics that are difficult or practically impossible to determine by experiment. paper presents results numerical titanium alloy Ti10V2Fe3Al (Ti-1023). behavior machined was modeled with Johnson–Cook constitutive eq...

In order to study the dynamic mechanical properties at high temperature and strain rate [1] of Q245R steel after corrosion, electrochemical accelerated corrosion test by constant current method tensile [2] High Temperature Synchronous Hopkinson Tensile device were carried out. The results show that has obvious strengthening effect softening effect, under certain conditions, becomes main factor ...

In order to quantitatively study the penetration capability of depleted uranium alloy, a simulation model bullet impact on target plate with FEM-SPH coupling algorithm was established by using LS-DYNA software, which combined Johnson-Cook intrinsic model, fracture criterion, and equation state conduct alloy bullets made tungsten high-strength steel penetrate at 1400 m/s initial velocity. The re...
