What is bright region between crack growth and post tearing?

Dear All, We carry out fracture test of Zr alloys. To distinguish crack growth during fracture test, we carry out heat tinting at 300 oC for 20 min at no load and then samples are torn apart to...

Is separation of J into elastic j nad plastic J correct?

As per ASTM-1820 J is separated in elastic J and plastic J. Elastic J is calculated as per eqn. Je=K^2*(1-v^2)/E and plastic J is calculated from area under load vs. plastic displacement. I want...

Side grooving in fracture specimens

ASTM E-1820 recommend side grooving after fatigue pre-cracking. But I think side grooving before fatigue pre-cracking is better because the fatigue pre-crack front will be more uniform. Also,...
