There are a few books, they are mainly in Swedish and concern forensic examinations of wounds and armor from the battle of Visby in 1361.

The book has some very good analysis on how fighters died, i.e. being struck a disabling blow and then repeatedly hit after they had fallen, based on post mortem damage to their bones and armor. Visby was several skirmishes, not a packed formation battle. Melees happened, which were a looser type of combat.

There is a book the covers the archaeological dig with drawing of the armor with theories of how it was constructed.

Here is a pretty amazing website that has reconstructions of the body armor.
