Modeling mechanical properties of carbon steels at high strain rates
Original language description
This work presents experimental and application possibilities modeling mechanical properties of carbon steels using LS DYNA 3D simulation program. The experimental part of the work is based on the taylor anvil test, which are applied to carbon steels ČSN41 2050 and TRISTAL steel in particular. These materials are the commonest steels used in cold forming processes and are compressed to the strain rate 1000 1/s. This paper contains the results of the Johnson-Cook constitutive equation by means of whichthe practical experiment is simulated. The results of simulation - the final surface of the deformed specimen - are compared with experimental results. Using the constitutive equation, the stress and strain curve is created for different strain rate.
