In liquids, the pressure exerted by the fluid reduces bending. There is extensional strain inside the crystal (causing bending) but the same extensional strain is present in the adjacent liquid as well. For volume conservation, extensional strain along x inside the liquid causes a corresponding strain along z, which exerts a normal stress onto the plate and thereby reduces bending.
