    strain in plastic hinge

    I have this diagram which gives the length of the plastic hinge. f is plastic modulus/elastic modulus. Then in my sheet the total angle of rotation of the hinge would be 2*phi. The depth of the beam is d. Then ε 1=d*phi/xy. Please let me know if I missed something.

    strain in plastic hinge

    The context here is that we have a structure on the sea floor and while working at the surface something can be dropped by accident and hit the structure. Our client specifies 5 kJ impact energy which is typical. The dropped object protection is provided to prevent the dropped object from...

    strain in plastic hinge

    Given the impact energy, I have need to calculate the deflection and plastic strain in a plastic hinge on a beam. It is a simply supported beam with the impact happening in the center. I have calculated the deflection but I'm stumped on calculating the plastic strain. Can't seem to find a...
