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 …
