✦ Synopsis


We construct the orthonormal bases of the Cosserat subspace Ä u À1 corresponding to the eigenvalue of in®nite multiplicity õ À1 for the ®rst boundary value problems of elasticity for a solid cylinder and a cylindrical rigid inclusion. These bases involve the Jacobi polynomials with dierent weight functions. An example of non-harmonic heat ¯ow past a cylindrical rigid inclusion shows that the sequence of Ä u À1 converges fast, thus, the Cosserat spectrum theory is an ecient method for solving elasticity problems of general body force or boundary loading.

By directly solving the Navier equations of elasticity, we obtain the discrete Cosserat eigenvalues and eigenvectors for the ®rst boundary value problem of a cylindrical shell. The discrete Cosserat spectrum approaches õ n À2 from both õ n `À 2 and õ n b À2 sides. It also reduces to a condensation p
