The linear contact bond … Nettet28. des. 2024 · The bond strength is determined by the tensile strength and shear strength . Bond shear damage occurs when the shear force exceeds the shear strength, which degenerates into the roll resistant linear bond model. At this time, the contact force remains stable, and the particles interact in a sliding and rolling form.
