| Abstract: | The expanding form of stresses and deformation near a crack tip as in the literature is extended to a general case, i.e., the Reissner plate crack/notches with multi-materials, arbitrary opening angles and various surface conditions. It is shown that the Reissner plate eigen problem is equivalent to a combination form of a plane problem and an anti-plane problem. |
| Keywords: | Reissner plate plane problem anti-plane problem eigenvalue fracture mechanics |
