Web18 Jun 2024 · Mathematical formulation of the first law of thermodynamics: (Relationship between internal energy, work and heat). The internal energy of a system can be increased in two ways. (i) By supplying heat to the system, (ii) By doing work on the system. Suppose the initial internal energy of the system = U1 If it absorbs heat q, its internal energy ... WebThe Elastic Wave Equation Derivation We can use our expression for the equation of motion and the relationship between stress and strain in an isotropic elastic medium to derive the elastic wave equation. In other words, we can substitute: σij = λθδij +2µeij into ∇·σ = ρ ∂2u ∂t2 For fully anisotropic media, we would need to substitute
