Notch tensile tests are conducted to calibrate the Johnson-Cook fracture criterion model. The wires made from SWRH82B high-strength steel with different diameters and shapes have different material performance due to different manufacturing and cold-drawing process. Therefore, two cross-section types (...
Johnson-Cook模型参数拟合 实际应用中,Johnson-Cook参数需要根据材料测试数据,通过参数拟合的方式得到。CurveFitter提供了Johnson-Cook塑性模型的曲线拟合公式,只需要输入塑性应变与应力值,即可以得到拟合的参数值。关于CurveFitter详情,参见《一款好用且免费的曲线拟合工具CurveFitter》与《曲线拟合的核心计算方法与CurveFitter的...
Hello,I have a Johnson Cook Model which has the function to transfer the visoplastic work to heat. Currently, I only want to see the temper due to the viscosity effect from Johnson Cook model. Also, I want to set initial temperature for my part. I want t
Johnson-cook模型 1. The results of this experimental work were used to define a new set of material constants for the strength component of the Johnson-Cook model for 20# steel. 根据材料在不同应变率下的试验结果,拟合了Johnson-Cook模型中的材料常数,并修正了应变率强化系数C,确定了20号钢的Johns...
Johnson–Cook strength modelJohnson〤ook (JC) high temperature strength material models have been widely used in Finite Element Analysis (FEA) to solve variety of hot rolling problems. In this paper, the temperature and strain rate related parameters of JC model were experimentally calibrated for ...
