| Abstract: | A set of accurate formulations are derived by theoretic analysis to calculate stress concentration of thin compound plate with circular hole which is filled with different material.Meanwhile,a set of simplified formulations are also given for convenience of real applications.The comparison among calculated results of stress concentration factors obtained by proposed accurate formulations,simplified formulations and finite element method by ANSYS shows that the proposed accurate formulations are reliable,and the simplified formulations have also good accuracy. |
