Rolling Shear Strength and Modulus for Various Southeastern US Wood Species using the Two-Plate Shear Test
… International Building Code (IBC), CLT material properties, especially rolling shear, would need to be explored. The increasing demand for softwood lumber, along with the increase of demand of CLT panel production, could place a burden and surpass the domestic softwood supply. Rolling shear is a …

Probing nanomechanics of aggrecan and the aggrecan-rich pericellular matrix of chondrocytes in cartilage
The mechanical properties of articular cartilage are associated with the extracellular matrix network of type II collagen and the proteoglycan, aggrecan, which in combination provide the tensile, shear, and compressive stiffness of the tissue. While the collagen network mainly provides resistance …
