Webb10 okt. 2024 · The Johnson-Cook (JC) model [ 17, 18] and simplified Johnson-Cook [ 15] constitutive models were used in the numerical analysis to describe the material from which the samples were made. The JC constitutive relation was complemented with a hydrodynamic equation of state in the Gruneisen form [ 19 ]. WebbAn empirical constitutive relation stated by Johnson and Cook (J–C) is extensively used to capture the strain rate sensitivity of the metals. In this work, model constants of J–C constitutive relation have been determined experimentally from the uni-axial tensile test.

Webb5 juni 2015 · Based on experimental data, a simplified Johnson-cook (J-C) model with failure criterion was established to describe the strain-rate dependent constitutive model for TC4T. Finite element (FE) models to simulate SHPB and quasi-static tensile tests were developed and validated by experimental results, respectively, to evaluate the … WebbExamples of such models are Johnson-Cook 7 (JC), Zerilli-Armstrong 8 and Bodner-Partom 9.
