    Tensile Load Equation


    A tensile load F is to be applied to the tie bar shown in FIGURE 2. The
    tie bar is 50 mm diameter. The surface of the bar has defects resulting
    from the manufacturing process, these have a maximum depth of 1.5 mm
    and have a shape factor of 1.4. If the fracture toughness of the material

    used is 120 MPa m0.5, determine the maximum load which can be
    applied if brittle fracture is not to occur. Use a factor of safety of 3.

    I have the stress being 627Mpa and the cross sectional area being 1.963mm so my force=stress x area and I get 1230801 which I think is 1.2Mpa which gives me final answer of 1200 Newtons.

    Could someone please confirm whether or not this is correct or not help me out here please.....

    answering this requires more knowledge about materials failure than I know offhand and am willing to go research. I suspect the same goes for the usual crew here.

    There's isn't a mechanical engineering forum out there you could pose this question to?

    Re: Tensile Load Equation

    Not that I know of the formula I have been quoted to find the force as attached and the stress I calculated to 627Mpa when I use the force value to find stress to check my answer it all comes back to the same results which would confirm the answers were correct but was looking for some clarification from someone more clued up than myself......
