“…First, the true stress--strain curve is modified according to cold working. Secondly, the value of the initial void volume fraction f 0 is changed (Oh et al, 2007). As noted, the value of the initial void volume fraction f 0 increases when the cold working rate increases (Oh et al, 2007).…”

“…Secondly, the value of the initial void volume fraction f 0 is changed (Oh et al, 2007). As noted, the value of the initial void volume fraction f 0 increases when the cold working rate increases (Oh et al, 2007). Figure 13 compares the experimental true stress-strain results with the numerical ones from finite element damage analyses based on the GTN model for different choices of f 0 for selected cases (CW = 25% and 50%).…”

“…Var et al [3] identified material parameters for Gurson-type and Lemaitre-type constitutive models for low alloy steel based on a hybrid global-local optimization technique. Chang-Kyun et al [4] used experiment and FE simulations for smooth and notched tensile bars, to calibrate the parameters in the GTN model. Malcher et al [5] undertook a numerical comparative study based on GTN original model and two recent enhancements that included shear mechanisms, employing mathematical and numerical strategies to calibrate the material parameters.…”

“…3 Kriging surrogate method is more efficient than the polynomial regression surrogate method in the sense that it provides more precise results with a smaller number of initial samples. 4 It was shown that except for the constant f n the reduction in diameter of the specimen predicted by numerical simulation was significantly sensitive to the constants f 0 , f c and f f .…”
