SAMSON, a two-dimensional finite element code, is based on small strain theory and is applicable to axisymmetric and plane bodies with arbitrary material properties. This code is a modification of the existing SLAM code. The solution procedure is especially suited for solution of large nonlinear problems in or out of core. This manual describes the theoretical basis for two-dimensional dynamic stress analysis of plane and axisymmetric media. It is particularly suited for handling problems with nonlinear material properties and a large number of degrees of freedom. In developing SAMSON, many of the features of the SLAM code were retained for solution of elastic problems including the direct stiffness solution method. For nonlinear problems an entirely new solution procedure was incorporated. New bar and membrane elements, an artificial damping option, and the capability to handle sliding-debonding interfaces were added. In addition to linear elastic materials, constitutive laws for a cracking composite material, such as reinforced concrete, and for soil with a capped yield surface were programmed.The solution procedure is especially suited for solution of large nonlinear problems in or out of core. This manual describes the theoretical basis for two-dimensional dynamic stress analysis of plane and axisymmetric media.
