This is the third mission for the student; they had more than 10 night landings already. It was a training flight and we were circling above [a crop field]; instructor told the student to divert to ZZZ; I asked what is the traffic pattern altitude and what runway are they going to use; the student was a little bit lost so instructor pointed [to] ZZZ. Instructor did the tear drop entry for left traffic rwy XY. On long final our speed was around 80 knots and our landing checklists were completed. Instructor corrected the speed & altitude and gave the student the control again on short final. Instructor was watching the airspeed and outside reference; it was a quick second when instructor applied additional backpressure the aircraft already landed hard; no bounce it was only a 1 hard hit; instructor announced 'my aircraft' and I had decisions to make whether to fly the aircraft again or land in the remaining runway. I decided to land the aircraft back on the runway because in my opinion it will be more danger to the public if my assumption that nose landing gear is hanging out were correct. I flew the aircraft for a second to slow down and hold up the nose as long as I can so we won't flip over; as I flew the aircraft again I immediately shut off the fuel source; and shut off the aircraft right away to prevent any fire because I know we will produce spark as we skid on the runway. I did my very best to control the aircraft and keep it on centerline. As soon as the aircraft stopped I told the student to evacuate as I secure the plane; and I turned on the master again to warn the CTAF that there's a disable aircraft on the rwy XY; I immediately called our dispatch; then I called the airport manager which was unavailable only answering machine. I turned on my flashlight to warn any possible traffic that might land on rwy XY. A Cessna landed and he stopped way far from the aircraft; the pilot checked me and my student. No injuries for my student and I.  Not even a scar; only a bit of bent metal.
DA40 pilot reported that the aircraft encountered a very hard landing.
