The report describes the development of a Fortran 4 computer program for finding shock-induced stresses in a three-dimensional piping system. Discretized equations of motion are formed by the finite element method. Input motions are support translations specified by response shock spectra. Maximum responses in individual modes and resulting octahedral shearing stresses at selected points are found for shock motions in three orthogonal directions. Extreme stresses, based on the square root of the sum of the squares of the modal stresses, are estimated for each input direction. An example problem is analyzed to demonstrate the use of the program.
