Calculate the punching stress P, if the constrained misfit is given as 1/3 and the shear modulus of the matrix is given as 5Pa?

Calculate the punching stress P, if the constrained misfit is given as 1/3 and the shear modulus of the matrix is given as 5Pa? Correct Answer 5Pa

The punching stress P is independent of the precipitate size and depends only on the constrained misfit Ɛ. If the shear modulus of the matrix is μ, the punching stress is given as P=3μƐ. Substitute the respective value we get the required solution.
