The general-purpose model combines concepts from multiple fields and describes various geological phenomena while satisfying fundamental laws such as mass conservation and energy conservation.
A general-purpose model combining concepts from rational continuum mechanics, fracture and damage mechanics, plasticity and poromechanics is devised in Eulerian coordinates, involving objective time derivatives. The model complies with mass, momentum and energy conservation as well as entropy inequality and objectivity. It is devised to cover many diverse phenomena, specifically rupture of existing lithospheric faults, tectonic earthquakes, generation and propagation of seismic waves, birth of new tectonic faults, or volcanic activity, aseismic creep, folding of rocks, aging of rocks, long-distance saturated water transport and flow in poroelastic rocks, melting of rocks and formation of magma chambers, or solidification of magma.
