Correction: Shin et al. Flow Stress Description Characteristics of Some Constitutive Models at Wide Strain Rates and Temperatures. Technologies 2022, 10, 52

In the original publication [1], the diagram in Figure 1a was described for both Abaqus and LS-Dyna in the text. However, a different diagram is necessary for LS-Dyna, which has been added now, and the corrected Figure 1 appears below:

Accordingly, the first paragraph in Section 3.1.2 has been corrected as follows:

After strain hardening, ductile materials often exhibit strain softening (see Figure 1), which eventually leads to fracture. According to the ductile damage model implemented in Abaqus [32] (Figure 1a), the overall damage (D) initiates from the maximum flow stress point and couples with the strain hardening constitutive behavior thereafter, which decreases the flow stress with strain after the maximum-flow-stress point. In GISSMO in Ls-Dyna [33] (Figure 1b), the mentioned coupling occurs when the damage (D) value reaches a critical value. Although the same notation (D) is used in both codes, their definitions differ [32,33]. In such coupled damage models, fracture is assumed to occur when the damage value reaches unity (D = 1). Elements with such damage values are eliminated in the explicit finite element simulation, which leads to a load drop in the simulated structure (the description of the damage localization is omitted here to abide by the subject of this study—constitutive behavior).

The authors state that the scientific conclusions of the original paper are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
