Numerical Analysis of the Strain and Stress State in Cylindrical Notched Tensile Specimens

We present the results of numerical analyses of the distributions of stresses and strains in specimens with notches of various sizes in monotonic uniaxial tensile tests. The applied method is based on the finite-element method and an elastic-plastic model of the material with hardening. The distribution of the principal strains, principal stresses, and maximum plastic shear strains in the plane of symmetry of the notch is shown.
