Hi everybody,
I have done some experiments on the fracture toughness in mode II of wood specimens using attached geometry;so using
formula KIIc= 5.11P(3.1415*a)^0.5 /(2BW) I was able to calculate the frcature toughness of wood, but I am quite suprised
why this equation does not iclude depth of the specimens and moreover, I think that I have obtained higher values for the
fracture toughnes values. Is there any other formulation for obtaining the fracture toughness in mode II for this specimen?
P.s. dimension of my specimens is 100*100*63mm
