| Popis: | A finite element program utilizing singularity-enriched elements was developed to determine the stress-intensity factors for an arbitrary V-notch in a linear elastic orthotropic beam. The special elements allow computation of the stress-intensity factors without recourse to an extremely fine element mesh. An application of the program was made to wood. A pilot experiment involving rectangular end-notched wood beams verified the program as well as demonstrated the utility of the program in predicting failure loads due to rapid crack propagation emanating from V-notches. The effect of varying wood properties on the V-notch stress-intensity factor was examined. A procedure to establish the failure surface encompassing V-notches and cracks under all loading conditions using the program is presented.
