Nettet11. feb. 2024 · The contact bond model is generally suitable for simulating soil materials. The linear parallel bond model provides the behavior of two interfaces: an infinitesimal, linear elastic (no-tension), and frictional interface that carries a force and a finite-size, linear elastic, and bonded interface that carries a force and moment. 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. asyl neussNettet12. nov. 2024 · The properties of the Linear Contact Bond Model model are shown below for reference.
