Theories of failure of stress
WebbFailure theories Failure mode – Mild steel (M. S) subjected to pure tension M. S subjected to pure torsion Cast iron subjected to pure tension Cast iron subjected to pure torsion … WebbThe maximum principal stress theory .. The theory associated with Rankine. This theory is approximately correct for cast iron and brittle materials generally. According to this theory failure will occur when the maximum principal stress in a system reaches the value of the maximum strength at elastic limit in simple tension.
