Temperature dependence of the elastic constants in the superconducting state is described on the basis of the Ginsburg-Landau theory. This approach shows very general character and allows to describe quantitative renormalization of the elastic constants in the superconducting state for different materials including non-conventional superconductors. Various examples (A-15 compounds, Chevrel compounds, CeRu2, Ba0.63K0.37BiO3, Yb3Rh4Sn13, Ca3Rh4Sn13, HfV2, some heavy fermion compounds and Sr2RuO4) are given.
