Deprecated. Deprecated in NX11.0.0. Use convertStressStrainYoungsModulusData(double[], double[], double, double, nxopen.MaterialUtilities.StressStrainData, nxopen.MaterialUtilities.StressStrainData) instead.

Convert stress strain data between the four types EngineeringStressEngineeringStrain, EngineeringStressEngineeringPlasticStrain, TrueStressLogStrain and TrueStressLogPlasticStrain. The output stressStrain data will be the same units as the input stressStrain data. The units of young's modulus should be consistent with the input stressStrain Data. The algorithm formula for converting from Engineering Strain to Log ( True ) strain is: Log ( True ) Strain = ln( 1 + Engineering Strain ) The algorithm formulas for converting from Engineering Stress to True Stress are: True Stress = Engineer Stress *(1 - Poisson's Ratio * Engineering Elastic Strain - 0.5 * Engineering Plastic Strain )^(-2) Engineering Elastic Strain = Engineering Stress / Young's Modulus Engineering Plastic Strain = Engineering Strain - Engineering Elastic Strain The algorithm formulas for converting from "True stress-log strain" and "True stress-log plastic strain" are: Log Elastic Strain = Log Stress / Young's Modulus Log Plastic Strain = Log Strain - Log Elastic Strain
