通过将位移连续性条件替换为面内应变和曲率的连续性条件，获得了三维线性动弹性中平面双材料界面上的应力及其一阶空间导数的条件。如果已经计算出另一侧的应力并解决了整个问题，则可以使用这些条件公式轻松计算多成分结构中界面一侧及其附近的应力，并且不能解决整个问题。
Conditions on stresses and their first spatial derivatives across a flat bi-material interface in three-dimensional linear dynamic elasticity are obtained by replacing the displacement continuity condition with continuity conditions on in-plane strains and curvatures. The stresses on one side of interfaces and near them in multi-constituent structures are readily computed using these conditions-formulae and not solving the full problem, if the stresses on the other side have been computed having solved the full problem.
