"A Thermal-Mechanical Finite Element Analysis of

May 18, 2020 · A coupled thermal-mechanical finite element analysis is performed in order to simulate orthogonal cutting of normalized steels. The Johnson-Cook cook material and damage parameters are utilized to define the behavior and failure of the material. Four cases are simulated with workpiece materials of A2024-T351, AISI 1045, AISI 4140, and AISI 9310. (PDF) Model-driven determination of Johnson-Cook material In this paper, an original approach was presented to identify the Johnson-Cook material constants (J-C constants). The Johnson-Cook model is one of the simplest models to describe the material behavior in machining. The five J-C constants are related Evaluation of an Analytical Model in the Prediction of Machining Temperature of AISI 1045

An Alternate Approach to SHPB Tests to Compute Johnson

Oct 07, 2020 · An Alternate Approach to SHPB Tests to Compute Johnson-Cook Material Model Constants for 97 WHA at High Strain Rates and Elevated Temperatures Using Machining Tests A Comparative Study of Analytical Thermal Models to Predict the Orthogonal Cutting Temperature of AISI 1045 Determination of Johnson-Cook material model parameters Jan 01, 2018 · It was found that optimized models outperformed the original models and the results were consistent with industrial measurements. Ãzel and Karpat [5] also employed an optimization approach in order to derive the Johnson-Cook material parameters for 4 different materials, namely AISI 1045 and 4340 steels, AA 6082-T6 aluminum alloy and Ti6Al4V titanium alloy. Finite Element Simulation and Experimental Analysis of Johnson-Cook formulation as a material failure model for AISI-1045 steel. ANSYS 11 was used, with SOLID element 164. The cutting tool has several geometries and the authors obtain forces, stresses, temperatures and the chip formation. Martinez et al [6] carried out thermo-mechanical studies, based on finite element, to simulate the
