Hi Experts,

I am reading "BASIC fracture mechanics" which is a very simple book. You must know this expression
sigmaY = KI/sqrt(2

Thank you in advance.

I am reading "BASIC fracture mechanics" which is a very simple book. You must know this expression

***pi***r)*cos(thita/2)*(1+sin(thita/2)***sin(3***thita/2)) and I think this is symmetric about thita = 0. My questions: Is the expression dirived from a rectangular (infinite or finite) plate with a crack at the center and under a symmetric load system case? There are different expressions For other cases, say non-symmetric cases?Thank you in advance.
