Pressure : Intensity of external forces acting on a body per unit area. For example : Atmospheric Pressure - Its the pressure exerted by air on surface of earth.
Stress is Internal Resistance offered by a body to external forces per unit area. Taking an example of Rubber Material. You apply some force and it deforms. But assume it doesn't deforms; then what happens, material is applying force equivalent to external force. That opposite force in termed as Internal Resistance and its ratio with area is called Stress.
