THM

THM is an acronym that can refer to several concepts depending on the context. In mathematics and theoretical computer science, THM is commonly used as an abbreviation for theorem, a formal statement that has been proven within a given axiomatic system. Theorems are central to mathematical reasoning and are accompanied by proofs that establish their truth under stated hypotheses.

In applied sciences and engineering, THM often stands for thermo-hydro-mechanical coupling. This term describes the interaction between thermal, hydraulic, and mechanical processes in materials and porous media. THM modeling is used to study heat transfer, fluid flow, and deformation in soils, rocks, and engineered barriers, with applications in geothermal energy, civil engineering, and nuclear waste disposal.

Other uses of THM exist but are less standardized; in some disciplinary literatures, THM can refer to thermo-mechanical concepts or to specific project names, companies, or publications where the acronym is defined locally. Because THM is context-dependent, readers should rely on definitions provided in the text to determine the intended meaning.
