Latest Patents

Liu is associated with 1 patent: “True Triaxial Dynamic Disturbance Test Device for Deep-Buried Hard Rock.” The device combines rigid static-load and dynamic-load assemblies to apply a long-duration static force and disturbance stress to a rock sample in a true triaxial stress state. A disturbance rod, disturbance hole, and sample clamp convert a point disturbance into a face disturbance. This approach is designed to better represent field conditions while reducing power consumption and enabling time-dependent dynamic disturbance testing.
