"Crack arrest" in fracture mechanics
"Crack arrest" in fracture mechanics
(OP)
Hi, I want to know if the fracture mechanics "crack arrest" concept is a property of the material or it depends on other factors, and if the "pop-in" shown by the fracture mechanics tests specimens just before they break has something in common with the crack arrest?
Thanks.
Thanks.





RE: "Crack arrest" in fracture mechanics
Qualitative tests as mentioned above are not a specific material property parameter, because the tests depend on stress conditions, and loading rate. These tests do allow one to characterize the fracture behavior under dynamic loading conditions in service.
