In this paper, the displacement field for a semi-infinite wedge anisotropic plate under transverse loading was first derived. The corresponding stress field was then determined. Stress singularities at the tip of the wedge were also obtained. To prove the validity of the derived theory, a clamped zero-degree twelve-ply carbon-fiber-reinforced-plastic (CFRP) plate with a wedge of 270 degrees was prepared as the test specimen. The electronic speckle pattern interferometry (ESPI) technique was employed to find the whole-field displacement. Well-matched condition between the theory derived and ESPI results was obtained. In contrast to an isotropic plate, the derived theory shows that stress singularities can be found not only above but also below 180 degrees of the wedge angle.
