The concept of eigen crack opening displacement (COD) can be defined as the COD of a crack in infinite plate under the tractions acting on the crack surface. By
We used bovine cornea as starting material,pepsin treatment in acetic acid solution to extract the mixture of type Ⅰ and Ⅴ collagens,and salt precipitation an
In this paper,we propose a two-grid algorithm for solving the stream function formulation of the stationary Navier-Stokes equations.The algorithm is constructed
