Based upon the theory of anisotropic plates, the unsymmetrical large deformation equations of orthotropic circular plates were derived. By using Fourier series,
The behavior of two parallel symmetric cracks in piezoelectric materials underanti-plane shear loading was studied by the Schmidt method for the permeable crack
The stability degree of periodic solution of nonlinear nonautonomous system was defined by means of the Floquet theory.A method evaluating the stability degree
A universal variational formulation for two dimensional fluid mechanics is obtained, which is subject to the so-called parameter-constrained equations (the rela
