Abstract:

"The Physics of Vibrating Strings." : Author's citation: "Some (numerical) results obtained with the algorithm are shown. Here the initial string profile (shown at the top of the figure) was chosen to be triangular, with the string at rest, as would be appropriate for a plucked guitar string. The kink associated with this pluck is seen to split into two separate kinks, one propagating to the left and one to the right, which reflect from the ends of the string. In our simulation we kept the ends of the string fixed, so the reflections are inverted." A program (in C) which calculates the time evolution of a guitar string: http://www.physics.purdue.edu/people/faculty/ng/tmp/cip/guitar_www.c A program (in C) which calculates the time evolution of a piano string which is excited by a blow from a piano hammer. The string is assumed to be perfectly flexible, and the hammer is modeled with a nonlinear force law, as appropriate for real hammers: http://www.physics.purdue.edu/people/faculty/ng/tmp/cip/hammer_www.c
