Investigation of mechanical properties and elucidation of factors affecting wood-based structural panels under embedment stress with a circular dowel i: analysis of the influence of various conditions on the embedment properties

Abstract Embedment properties are vital to timber structural designs, and many types of wood-based panels have been developed for diverse uses. Comprehensive systematic studies regarding the embedment limited. In this study, a jig that allows observation fracture processes is developed, monotonic tensile test conducted on plywood, oriented strandboard (both strong weak axes), particleboard, medium density fiberboard, hardboard. The parameters used in dowel diameter, pilot hole size, end edge distances. effects these (i.e., failure mode, ductility, maximum stress, yield stress) discussed comprehensively. mode determined by distance. At sufficient distance, ductile occurs, load maintained until remaining distance reaches certain value. stress analyzed quantitatively via standardized multiple regression analysis. results suggest following: (i) ratio in-plane strength internal bond related behavior; (ii) fiber direction, levels affect spread pattern pressure.
