I am reading "BASIC fracture mechanics" which is a very simple book.
You must know this expression
sigmaY = KI/sqrt(2*pi*r)*cos(thita/2)*(1+sin(thita/2)*sin(3*thita/2))
and I think this is symmetric about thita = 0.
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
Thank you in advance.
