The aim of this paper is to introduce some convergent expansion formulae of solutions of two-dimensional linearized elasticity equation so-called as Navier’s equation around a crack tip and a tip of thin rigid inclusion, explicitly. In particular, three boundary value problems are treated; the first case is that a homogeneous and anisotropic body has a linear crack; the second case is that two different isotropic homogeneous bodies have an interfacial crack under the non-penetration condition and the frictional condition in Coulomb’s law; the third case is that a homogeneous and isotropic body has a rigid line inclusion. Moreover, the paper intends to clarify how the order of singularities in expansions is determined, which depends on the geometry of the material, the governing equation, boundary conditions, material properties, and so on.
