Hi
our extensive investigation on analysis of damaged structures led to the conclusion that inserted in this question. According to our finding the stress concentration at fracture threshold is a constant (square root of pi), and is independent of the shape of damage, material property, and etc. In view of this finding all damages may be treated point wise and hence great saving in time and expenditure.
I would be very pleased to comment in line or in opposition? specially comments based on tests are highly appreciated.
In this question by stress concentration, I mean stress concentration factor.
HI
This is an important question that can change the philosophy behind the failure of structures. So I ask the academic community to enter their understanding, memory, feeling, and else regarding the question.
