Research on calculation of stress intensity factors in a cracked plate

In order to find the solution for the stress intensity factor(SIF),a method to calculate the SIF at the tip of crack of a finite plate with a central through-crack based on the maximum crack opening displacement was proposed.Firstly,based on the Westergaard stress function,for a central through-crack in an infinite plate under two uniform tensile loads,the mathematical function relationship between the normal maximum crack opening displacement...
