The basic equation of elastic mechanics at plane stress state is determined by the mechanical characteristic of orthotropic plate. The stress boundary problem about the orthotropic plate with a crack is solved by using the complex function method. To take Mode I crack problem for the typical example, the general solution method is discussed for the stress and deformation near the crack-tip. And the singular stress and strain fields are derived for the orthotropic plate. The crack opening displacement is yet obtained to have a relation with the material characteristics. %K 正交异性板,裂纹端部,复变函数,应力和应变,裂纹张开位移
