RPSL1D (A One-Dimensional Version of REPSIL).

Abstract

RPSL1D is a one-dimensional version of REPSIL, a computer program which calculates the large plastic deformation of thin Kirchhoff shells, The REPSL1D program is more efficient than REPSIL for axially symmetric shells (shells of revolution) and slab symmetric shells. It has been used most frequently for deformation calculations in laterally symmetric beams. The numerical algorithm differs from that of REPSIL in that external, artificial, points are used to define boundary conditions, and that forces are computed between mesh points as well as at mesh points. This gives a better simulation of clamped ends and a more compact, more stable system of difference equations. The report gives instructions for using RPSL1D. Listings of the program and the companion plotting program are given. Two example problems are discussed with tabulated input and output. A number of options, primarily for beams, are tabulated and discussed.
