"The yield point is the point on a stress―strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Yield strength or yield stress is the material property defined as the stress at which a material begins to deform plastically whereas yield point is the point where nonlinear (elastic + plastic) deformation begins. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible. "

In other words, this is the minimum amount of force you can apply to a material before it gets bent out of shape, for practical purposes we could use this value to calculate feats where materials such as steel get dented or seriously bent, but not outright torn or destroyed.
For reference, steel is listed on the aforementioned wiki page as having a yield strength of 250 Megapascals, applying the same logic used by the OBD and us by extension, we can infer that the energy required to bend 1cm3 of steel is 250j (you may notice the value is greater than the one for the fragmentation of steel in NF that we use, but this is because the general strength of steel varies depending on the way it is made).
One notable calc that makes use of this is batman kicking down a prison door which is currently accepted in his profile, should be noted that "Elastic limit" and "Yield strength" are interchangeable terms they both practically refer to the same thing.
