| Abstract: | In this article, the multivariable plane elasticity variation principle for divided region is presented, which includes the boundary conditions for each divided region and covers five classes of equations such as equilibrium, stress_stress function, displacement_strain, compatibility and material behaviour. The principle is the most general variation principle for divided plane elasticity. |
