Abstract
The theoretical method can be used to obtain satisfactony result of calculating the notch root stress and strain under uniaxial loading.But it is not suitable for multiaxial loading conditions.For this,this paper uses elastic-plastic finite element software ANSYS to calculate the notch root stress-strain threshold and determines the dangerous point location.The MPC unit is used in the process to simulate the bending torsion coupling loading and.reduce the error caused by the loading.According to the calculation and analysis results,the influence of the notch depth on stress and strain is studied and the relationship between the notch depth and the notch root strain component is quantitatively given.关键词
