Latest Patents

The provided information lists one patent for Cheng Meng: “Method for Evaluating Rock Compressive Strength Based on Cuttings Mineral Composition, Nano-Indentation, and Friction Tests.” The method combines measurements of mineral composition, nano-indentation behavior, and friction to estimate rock strength. It uses energy-conservation principles to calculate mineral elastic moduli and plane-strain fracture toughness, then integrates mineral parameters according to their proportions to derive rock failure characteristics. These characteristics and the rock friction coefficient are used to calculate uniaxial and triaxial compressive strength. Cheng Meng is credited with 1 patent in the supplied data.
