Hi, I want to check when WC-10Co brittle material fractures in Ansys Workbench. I want to simulate an end mill tool by applying a radial force on it's tip. I have the values of the Transverse Rapture Strength and the K1C.
Can I consider the Maximum Normal Stress Theory which says that when the maximum principle stress exceeds the TRS, failure occurs ?
Thank you.
Thank you Mr. Reddy.
I my case, I want as simple as possible, I don't want to see the failure behavior and how it cracks. The only think I would like to know is when getting the results, to know yes know it will break.
Can I say that: when the maximum principle stress reaches the TRS value, fracture occurs ??
Bilal,
Facture of brittle materials is mostly due to tensile failure, while ductile materials yielding is mostly due to shear failure.
So yes, putting it simple, if the maximum principal stress reaches the fracture strength of the material, it will fail.
Hope this helps.
Best wishes.
Aaron
