The comparison of the theories of failure results in plotting various curves, as area bounded by the curve increases thus
What will be the tensile yield strength if the factor of safety is taken as 2. The values of principle stresses σ1 = 35 MPa andσ2 = -115 MPa were calculated from the Mohr’s circle. Use Maximum distortion energy theory.
Match the following Theories:
Various Theories of Failure are derived and are used for the purpose. The theory highly recommended is
A Particular section of steel shaft is subjected to maximum bending stress of 160 MPa and a maximum shear stress equal to 60 MPa. The yield point in tension of the material is 400 MPa. If maximum principal stress theory is used, the FOS will be _______.
In an industrial application, FEA analysis was integrated with failure theories to design materials. So the equation derived or used for safe design is;
