General Solution of Mixed-mode I-II-III Crack-tip Stresses for Orthotropic Materials

General solution of the crack-tip singular stress fields has been discussed for the orthotropic materials under the mixed mode I-II-III loading. The essential equations of linear elastic mechanics are determined for three dimensional space problems. Typical stress boundary problem for cracked orthotropic plate is considered to be solved by using complex variable method. The general expressions of three dimensional crack-tip stress fields are derived finally.
