摘要: Abstract The through-thickness variations of stress and strain concentration factors for plate with small central notch, circular notch or double U-notch, subjected to uniaxial biaxial loading have been systematically analyzed by using three dimensional finite element method (3D FEM). It is found that the maximum occur on mid plane only in case thin plate. However, thick plates, sites these values are near surface. Furthermore, this site more close surface radius and/or large thickness. increase decreasing ratio at interior, while, opposite trend
