INTRA-RING COMPRESSION STRENGTH OF LOW DENSITY HARDWOODS

Engineered wood composites are being crafted with increasingly smaller and smaller components, yet a search of the literature indicates a lack of intra-ring mechanical property data for almost all commercial wood types, particularly the underutilized low density hardwoods. In addition, there is no u...
