摘要: In this paper static and dynamic loading of Charpy V-notched pre-cracked specimens was simulated by FEM analysis using elastic-plastic material equation a cast ferritic steel. The results 2D plane strain, stress 3D modelling are presented discussed here. Different impact velocities were applied in the calculations. Contact situation considered between hammer specimen, as well specimen anvils. calculation analysed compared with experimental load-deflection curves. case not only calculated curve, but also magnitude inertia peak, load oscillations, loss contact effect showed good agreement results. possibility for predicting fracture toughness values on basis is
