“…The damages responses were predicted using uncoupled damage model. The damage accumulation is assumed to not affect material plasticity and is described using a weighting function (Hu et al, 2018;Lou et al, 2012;Pater et al, 2020;Talebi-Ghadikolaee et al, 2020). The damage initiation is described based on the normalized Cockroft-Latham ductile fracture criteria (Pater et al, 2020;Talebi-Ghadikolaee et al, 2020):…”

“…Based on these facts, uncoupled DFC is used in this study. Specifically, the DFC was proposed by Cockcroft and Latham [32,33], Brozzo [34,35], Ayada [36,37], and Rice and Tracy [38,39]. The specific forms of these DFC are given in Eq.…”

“…As can be seen from Eq. ( 1)-( 4), Cockcroft and Latham criterion [32,33] argued that that fracture is associated with maximum principal stress 𝜎 1 , and equivalent stress 𝜎 𝑒𝑞 . The criterion was proposed considering a tensile cylindrical specimen.…”

“…Metals are denser than composite or graphite, so an inherent reduction in their thickness is essential. Aluminum, nickel, copper, and titanium alloys are frequently used to manufacture BPPs [3,8,9]. Due to their superior mechanical properties and low gas permeation, stainless steels have been more commonly used in research [10].…”
