During the woods battle between Thor and Iron Man in the 'Avengers' movie, they get down to slugging it out toe-to-toe. Iron Man tries to punch Thor, who instead catches Iron Man's punch in mid-swing and proceeds to crush his gauntlet.
Iron Man responds by blasting Thor in the face using that now crushed gauntlet.
How can this be? Shouldn't the gauntlet have been disabled?
Note/Edit In the movie 'Iron Man', Stark shot up his own workshop while dressed in civilian cloths (no Ironman suite) and with only one gauntlet on. The power source/repulsor energy seems to be coming from the vambrace on his forearm, not the armored suit he wasn't wearing.
