Numerical modelling of 3D hard turning using arbitrary Lagrangian Eulerian finite element method

چکیده
In this paper, 3D Finite Element Method (FEM)-based numerical modelling of precision hard turning has been studied to investigate the effects of chamfered edge geometry on tool forces, temperatures and stresses in machining of AISI 52100 steel using low-grade Polycrystalline Cubic Boron Nitrite (PCBN) inserts. An Arbitrary Lagrangian Eulerian (ALE)-based numerical modelling is employed for 3D precision hard turning. The Johnson-Cook plasticity model is used to describe the work material behaviour. A detailed friction modelling at the tool-chip and tool-work interfaces is also carried. Work material flow around the chamfer geometry of the cutting edge is carefully modelled with adaptive meshing simulation capability. In process simulations, feed rate and cutting speed were kept constant and analysis was focused on forces, temperatures and tool stresses. Results revealed good agreements between FEM results and those reported in literature about experimental ones.

Numerical analysis of fluid sloshing in tank wagons is amongst essential research ideas that are focused by railway engineers. The free surface of fluid becomes unstable and turns into a dynamic complex non-linear problem for fluid-structure interaction (FSI). In this paper, initially, the dynamic response of the tank, including lateral force analysis and pressure distribution during braking, i...

متن کاملPipeline upheaval buckling in clayey backfill using numerical analysis
Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...
