If a shear force is acting on a rectangular beam, how do I use the value of the shear modulus to calculate if the force applied will fracture the beam? Below I've submitted the data involved.
The shear force applied is 1000 N and the cross section area is 28 mm.
So the shear force applied is 1000/28 N/mm^2 = 35.7 N/mm^2.
As far as I'm concerned the shear modulus tells me how much force I can apply per mm^2 before it fractures. Am I right?
Material: PVC
E-modulus: 1300 N/mm^2
Poisson's ratio: 0.35
Applied shear force: 100 N
Resisting area: 28 mm^2
Shear modulus: E = 2G(1+v) --> G = E/(2(1+v)) = 1300/(2(1+0.35) = 481 N/mm^2
