A plate with lateral load

When the plate deforms more than 0.2 - 0.3 times the thickness, we have to take into account the shell (membrane) forces. It is here we have to utilize the 2. order plate theory.

The 2. order plate theory can be applied for thin plates satisfying the following criterias:

By introducing the shell(membrane) forces, the plate can have an increased load bearing capacity compared to linear 1. order theory.
