The dimensions and material properties of the AISI4340 plate made of steel and containing a crack in the center are as given below. This plate has a defect of a 1mm as an initial crack. Calculate the stress intensity factor for the as the plate is subjected to a tensile load of P = 240N. Plate thickness B =6 mm. Plate width W = 2b=76 mm.SIF for center crack?2a2b?K1 = βσ√(π a)β = √(Sec((π a)/(2b)))
