Conversion between the numerical simulation and the calculation using the Deformation Energy Ratio approach.

Abstract

In numerical simulations and calculations, material curves are defined in different ways. A direct transfer of quantities between them is inaccurate, requiring a proper transformation of key values. The Deformation Energy Ratio approach is based on well-established mechanical principles, such as Neuber's rule and the Equivalent Strain Energy Density method, which express deformation energy as a function of stress and strain. This approach accounts for material conditions in both analyses and enables a more precise limit adjustment. Its simplicity allows for application in both analytical and numerical solutions.•Allows conversion of values between numerical simulation and calculation for any steel.•It takes into account the influence of material properties, thus comprehensively considering the effects of different factors.•The verification has presented a high accuracy of the values obtained. The average deviation is <5.0 % and the maximum deviation is 5.6 %.
