| Abstract: | According to D-M model, a common formula of crack tip opening displacement COD for a Griffith crack stretched to a symmetroid load is derived by using weight function method. The formulae of COD for four loading cases are obtained by using it. The presented method is veery simple. The given results are very useful in engineering. |
