The Numerical Simulation Technology in the Cutting Process of Alloy Steel AISI4340

Abstract

Using the finite element analysis software ABAQUS, simulation experiments on physical nonlinearity, geometric nonlinear, nonlinear finite element, elastic-plastic in the cutting process are conducted, which realize the separation of chips and working piece combined with material failure criterion, shear failure, adaptive grid technique in ABAQUS. Meanwhile, the stress field, strain and temperature field and cutting force in the cutting simulation are obtained consistent with cutting theory.

Fluid-solid-ablation coupled calculation of hypersonic vehicle based on rbf grid deformation method

“…In the study of Yang et al [21] , the modeling of shape changes caused by ablation recession was conducted, and the effects of these changes on the flow structure and aeroheating mechanisms were investigated. Wang and Gao [22] conducted finite element calculations on the solid field based on a linear ablation model and simulated the steady-state flow field of the aircraft under constant calculation conditions. Cai et al [23] used the birth and death element method to perform unsteady finite element numerical simulations on a component of a spacecraft, and the calculation results were consistent with actual data.…”
