Peruse the Historical forums on the definition of 'broadsword'. You may be ..suprised. 'Broadsword' like 'chainmail' is a misconcieved term, a broadsword simply means a sword created to be used in war. Any sword short of slimmed down civilian swords such as a rapier or the like (but even they I believe were less flimsy then you would think) would be described as a 'broadsword'.
No sword short of possibly the Estoc is going to put a scratch on any armour worth it's salt. None.
Maces, picks, axes, lances. They are pretty much your only chance to put a mark on a decent set of plate, and chain is gonna resist 'most any cut, leaving only impact damage too.
And I believe (though I welcome contradiction from the residents of the previously mention board) that a 'bastard' sword actually referred to most swords including what we would call a longsword from a certain era, they were all able to be used in one or two hands.
/Just a couple of things from a lurker who wouldnt like misconceptions furthered.
Aye, strictly speaking I've seen so many various misconceptions on the topic of weaponry names, that I lost count of it. And again, if you have a special weapon on your mind you better describe it and not just give a “common” name. Though there are plenty of them like a “longsword” (a medium length sword with a double-edged blade), a greatsword (a two-handed sword of the same type but longer and broader), a short sword (anything from a long dagger to something resembling a Roman gladius), and so on.
The term “armor” (even plate armor) could be interpreted in many different ways as well. Of course, if we are speaking of extremely heavy cavalry armor, which left the knight immobile or a completely stiff tournament set, which did not even let him to move his hand, no weapon what so ever could possibly damage it save for a real hammer.
If we are speaking of anything less “heavy-duty” even cut weapons like axes or broadswords should do fine. Now there's the time to determine what the word “broadsword” means. Actually, I could never find the appropriate historical term for the weapon, which looks roughly like a two-handed longsword with an extremely broad blade designed solely for delivering cut blows. They were used to cut through armor which was impossible for any lighter weapons. Any other words, a broadsword is something of an intermediate between a longsword and an axe.
As for the bastard swords, it has some very distinct differences from a longsword. A longer blade (closer to that of a greatsword), a handle designed for wielding with both hands and most importantly – an elongation of the handle with a heavy counterbalance. Those long cavalry swords which could be use as two-handed ones cannot be called bastard swords.
