What happens when plates are bent?
A trench has formed at the bend. All that folding and bending makes rock in both plates break and slip, causing earthquakes. As the edge of the oceanic plate digs into Earth's hot interior, some of the rock in it melts.
What is plate bending theory?
Bending of plates, or plate bending, refers to the deflection of a plate perpendicular to the plane of the plate under the action of external forces and moments. ... Once the stresses are known, failure theories can be used to determine whether a plate will fail under a given load.
