This was a topic of discussion soon after the 911 attacks, where we discussed amending the standards for cockpit doors. It was required that the doors be modified to be impenetrable by terrorists, but still accessible by rescue teams, should the pilots actually simply need to be rescued out of a cockpit after a crash. Make the door impenetrable, but not so much so that rescue crews can't get in - eventually. I recall that a minimum specified energy had to be expended (measured in Joules, if I recall) to get into the cockpit, and having expended that amount of energy, entry was somewhat assured. I don't think "firm whack" was a standard, but I recall a lot of discussion about swinging a fire axe!
