Collecting Woody Slash

Interfacing Forest Engineering with Bioenergy Production

Abstract  Woody biomass from forestland, urban greenbelts, and residential areas has the potential to provide more than 150 million tons per year of cellulosic feedstocks for biorefineries, pellet fuels, and fermentation. Production sites range from urban lots to large wildland forest tracts. Destinations range from small urban boutiques to large remote industrial complexes. The systems, …

Catastrophic failure from parallel to grain tension, not shear

Mode of Failure Model for Cutting Solid Section Biomass

Abstract Solid section biomass, such as wood and the node-zone of crop residues, has distinct modes of failure when loaded in cross grain shear. Shear bar design plays a part in determining what the failure mode will be at a given depth of penetration. Other factors include shear location relative to an unconstrained end and …
