Yield Strength

A steel plate having yield strength of 550 MPa, is subjected to biaxial state of stress as σx = σ and σy = -2σ. Using distortion energy theory and considering the factor of safety...

The endurance limit of a specific grade of steel is same as its yield strength. The ultimate strength of this grade of steel is twice of its yield strength. A component made of thi...

A plane-strain compression (forging) of a block is shown in the figure. The strain in the z-direction is zero. The yield strength (Sy) in uniaxial tension/compression of the materi...

At a critical point in a component, the state of stress is given as σₓₓ = 100 MPa, σᵧᵧ = 220 MPa, σₓᵧ = σᵧₓ = 80 MPa and all other stress components are zero. The yield strength of...

A machine component made of a ductile material is subjected to a variable loading with σ_min = -50 MPa and σ_max = 50 MPa. If the corrected endurance limit and the yield strength f...

The principal stresses at a point in a critical section of a machine component are σ₁ = 60 MPa, σ₂ = 5 MPa and σ₃ = -40 MPa. For the material of the component, the tensile yield st...

A test specimen is stressed slightly beyond the yield point and then unloaded. Its yield strength
