The success of a FE model for metal cutting process is strongly dependent on the accurate characterization of the workpiece material, under similar conditions as those found in metal cutting. In this paper, dynamic shear tests using a Gleeble machine have been performed on 4 mm thickness disks of AZ31B-O magnesium alloy, using a special designed tool. In order to include the effects of the cryo...

The accuracy of a machining model depends on the capability this to describe physical phenomena associated real system. This includes material constitutive and approach used field flow in cutting. In paper, high speed (HSM) Ti6Al4V titanium alloy is developed. cutting proposed considering influence strain hardening, strain-rate, temperature, state stress (e.g., triaxiality Lode parameter) plast...

This research focuses on the study of simulation capabilities lagrangian (LAG) model and Smoothed Particle Hydrodynamics (SPH) for orthogonal dry machining aluminum alloy Al6061-T6. A three-dimensional finite element was developed verified using experimental data from published literature. The numerical models were boundary conditions via modeling in ABAQUS/Explicit 6.14. cutting simulations ca...

Bone drilling is a routine operation in surgeries, such as neurosurgery and orthopedics. However, the excessive temperature may cause severe thermal damage to bone tissue. Therefore, determination of tissue can reduce harm caused by damage. A time-varying field simulation model was set up ABAQUS software this paper, based on Johnson-Cook model. Then it validated with experiments cortical fresh ...

Abstract Friction stir spot welding is a solid-state joining process that has attracted significant attention particularly in the field of lightweight, low melting alloys. These materials include alloys Aluminium and Magnesium amongst many others which are great importance to aerospace automobile industries. The friction complex thermo-mechanical multiphysics phenomenon currently intense resear...

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...

Abstract The study was based on the analysis of stamina steel flat bottom section transport warships, burdened by spherical pressure wave from non-contact explosion TNT at a distance 20 m under keel. This aims to determine mass required break hull. task solved finite element method (FEM) explicite using CAE program [1], in which hull’s modelled as thin shell space. burden with impulse specified...

A comprehensive benchmarking study has been carried out to determine the influence of mesh formulation and chip separation methods on reliability accuracy finite element modelling large diameter drilling operations. The Coupled Eulerian–Lagrangian updated-Lagrangian (with deletion) formulations available in ABAQUS/Explicit, together with re-meshing) DEFORM 3D are compared by simulating through-...

Abstract This study presents an investigation of the plunge stage in joining AZ31B magnesium alloy with friction stir welding using two different 3D finite element models based on Arbitrary Lagrangian–Eulerian formulation and Coupled Eulerian–Lagrangian formulation. The investigations are made ABAQUS program. Johnson–Cook plastic material law Coulomb used both models. Models compared terms temp...
