Thank you Sir.

From past papers, I found that selection of load at high AE energy counts near peak load. Is any ASTM, ASME or formulation guidelines to find AE J-integral from that selected load?

Arvind Bind

You can detect point on crack initiation and hence initiation toughness but you can't generate complete j-r curve.

Thank you Arvind Sir !!!
