Engineering estimates of crack opening displacement for non-idealized circumferential through-wall cracks in pipe

•New h2 values of GE/EPRI method for circumferential non-idealized TWC are proposed.•New elastic CODs are proposed to predict COD of circumferential non-idealized TWC.•New COD estimate based on ERS method for circumferential non-idealized TWC is proposed.•The proposed estimates for CODs are validate...
