How to obtain stiffness value of a plate

hi all 

As you can see in the picture below, there is a simple plate which is constrained from the left side and is applied force from right side?

I would like to get the stiffness value of the plate from Optistruct. 

I want to compare with the hand calculations. 

Is it possible to see one stiffness value for whole plate?

Best Regards

    Hi

    Solver does not write out stiffness per element.

    But you can check the stiffness of the whole part as you would do for a coupon tensile test.

    You output the total force, in fact this you already know, and displacement resultant of the applied load..

    If the relation is linear, the stiffness  is equal to the ratio (force / displacement)

     

     

    I hope this is helpful

     

    Regards
