Derivation of constraint-dependent J–R curves based on modified $$T$$ T -stress parameter and GTN model for a low-alloy steel

Crack-tip constraint analyses and constraint-dependent LBB curves for circumferential through-wall cracked pipes

“…1. The true stress-strain curve of A508 steel at room temperature (Yang et al, 2012;Wang et al, 2013).…”

“…Based on the solutions of constraint parameter * and the constraint dependent J-R curves of A508 steel obtained by Wang et al (2013), the constraint-dependent LBB curves for pipelines were obtained and analyzed.…”

Fiber orientation effect on fracture toughness of silk fiber-reinforced zeolite/HDPE composites

“…Upon 0° the EWF continues to decline even though it is not as sharp as the decrease in value from 0 to 22.5°. The EWF parameter is equivalent to J IC in the J-integral method, which shows material resistance to crack initiation [32][33][34]. Therefore, Fig.…”

“…The non-EWF (βw p ) on Z-HDPE composites (without SF) is equal to 3.67 MJ/m 3 which means lower than non-EWF material at fiber orientation of 0, 22.5, and 45°. The βw p parameter is equal to ¼. dJ/da which is the slope of the J-R curve in the application of the J-integral method where a is the initial crack length [32,33,[35][36][37]. The dJ/da is a parameter that represents toughness against crack propagation.…”

Investigation on the constraint effect on the fracture toughness assessment of stainless steel AISI 304L thin sheets

“…Considerable efforts were made within the scientific community for determination of an intrinsic criterion for fracture toughness assessment of ductile materials (Bensaada et al, 2018;Wang et al, 2013). It has been recognized that the fracture mechanical parameters are dependent on the geometric parameters of tested specimens (Brocks et al, 2010).…”
