| Abstract: | A study is presented concerning the effect of mesh geometry upon the accuracy of finite element solutions for fracture problems. Suggestions are given for the determination of the optimum mesh for several types of problems using linear displacement and quadratic displacement quadrilateral demonstrated that merely using smaller elements will not necessarily improve solution accuracy. |
