THE EFFECT OF SELECTED MATERIAL PARAMETERS ON THE STRESS AND STRAIN STATES IN THE PROCESS OF CUTTING A SHEET PLATE WITH CIRCULAR CUTTERS
The influence of the type of material on deformations and stresses of sheet metal in the process of cutting with numerical tools is presented. The Cowper-Symonds model is used to describe the properties of cut sheet-plate and the influence of two parameters C and P on the state of stresses and strains in steel cutting element. Numerical results were obtained by the finite element method (FEM) making use of the ANSYS LS-DYNA ver. 9.0 program, based on the explicit time method.
