I want to use the Point stress criterion in order to determine the notched strength for composite laminates with different hole size, But I dont know how Can I determine the characteristic distance d0 in Whitney and Nuismer model !!
hello dear Abdelhak
i can not write the formula but i think you know the formula to determine it. if you have the rate of d0 and time you can find the next "d" and with this steps you can find waht you want.

I think you need to have a solutions of stress distributions for different hole sizes for a structure element under consideration, As an example you can use paper http://www.sciencedirect.com/science/article/pii/S0013794406004565
