Stress changes the shape or breaks (fractures) rocks whereas bending leads to folding
Deformation
Folding is the bending of rock layers due to stress.
Stress and faults are both caused by tectonic plates.
They are caused primarily by shear stress.
Some causes of physical change could be linked to the types of mechanical stress: shearing, compressing, bending, twisting, etc.

The bending stress in a beam is inversely proportional to the section modulus.
-> when a structural body gets deviated from its original position or from its centroidal axis due to externally applied load,then it is termed as BENDING->DIRECT STRESS is the stress which act normal to the plane-> stress and bending are the two different things. stress produced by load per area & bending is the effect produced by load and stress.
direct stress is a stress normal to the cross section, A, and is the result of an axial load, P. direct stress = P/A Bending stress also acts normal to the cross section but varies from tension on one side and compression on the other. and is the result of a bending moment, M. bending stress = Mc/I where I is the area moment of inertia and c the distance from outer fiber to neutral axis
Folding
tensile stress is due to just the tension in the load whereas breaking stress can be due to breaking,shearing or compression!
