FEMFAT Plast Extension Module: Considering Local Plasticity
Calculating elasto-plastic stress from linear elastic analysis results.
EMFAT plast calculates the elastic-plastic stress around the notch area based on the results of linear elastic analysis using the Neuber correction. The Neuber rule is a method that demonstrates the relationship between linear and nonlinear stress and strain, allowing the representation of the Neuber hyperbola using Young's modulus E and nonlinear strain εplast. To represent the hysteresis loop of the cyclic stress-strain diagram (using the cyclic hardening coefficient K' and cyclic hardening exponent n'), the Ramberg-Osgood rule is used to calculate the nonlinear stress as the intersection point with the Neuber hyperbola. This eliminates the need for FE analysis considering material nonlinearity for local plasticity, allowing the elastic-plastic stress to be corrected with FEMFAT plast. Additionally, FEMFAT plast enables a reduction in computational effort for FE analysis. FEMFAT plast is compatible with FEMFAT basic, FEMFAT max, and FEMFAT spectral. *For more details, please download the PDF or contact us.*
