Mode I Elastic Solution of Cracked Composite Plate

[摘要] The basic equation of composite mechanics has been established according to the orthotropic material properties. The analytic function of the complex variable including the material parameter is analyzed fully. Boundary problems of composite plate with Mode I crack are solved by using the complex variable method. The formulae for stress fields and strain fields are derived. The derivation of elastic displacement fields is carried out, and the whole displacement expression is determined by the complex variable function.
