This research is designed to establish rational engineering design procedures for wood pallets. The authors role in this endeavor is to determine the stiffness and strength of notched stringer members of pallets as functions of notch geometry, material properties, and loading conditions. As part of this effort, the author developed the FE program described in this paper to compute displacements and stresses in wood members of any geometrical shape which are under arbitrary plane stress or strain-loading conditions. This computer program is to be applied to the notched-stringer problem. Details of the program development, user instructions, and program listing are presented in this report. The program was verified by a comparison of FE predictions of displacements and strains in center-loaded, double-tapered wood beams with data available in the literature. This comparison is presented in another paper.
