There is the thesis in english that explains for some stuff, physical modelling is very hard and less effective than easier to understand and implement methods. http://smack.berlios.de/thesis.pdf The thesis isn't great but it was a huge amount of work, and it's full of maths, sound samples, etc. ;) The guy in this case is me. :) You can use karplus-strong (physics inspired..) very easily for string synthesis but modelling the bow is still a huge task.
