Hi, I was wondering what the equation is to calculate theoretical fracture strength if you know the elastic modulus and flexural fracture stress?
The flexural fracture stress for ordinary (i.e., soda-lime) glass is around 30–70 MPa. Based
purely on the elastic modulus, what is the theoretical fracture strengthof this glass? How can
the difference between reality and theory be explained?
The elastic modulus for glass is 69 GPa.
Thanks
