Strain Rate Influence on the Elastoplastic Damage Behaviour of Nodular Cast Iron

Due to the high ductility and fatigue strength, the ductile or nodular cast iron is widely used for many structural applications. Numerous investigations have been carried out during the past decades to determine influence of microstructure on the mechanical behaviour of this material under monotonic, cyclic and fatigue loading [1]. However, the literature regarding the dynamic mechanical behaviour of nodular cast iron is limited. This paper presents an experimental and numerical investigation of the dynamic elastoplastic damage behaviour of the nodular cast iron grade EN-GJS-400-18-LT. The experimental procedure includes static and dynamic tensile tests at different strain rates on the flat and cylindrical specimens, as well as three point bending tests. Thereafter, numerical modelling of deformation and failure process of the specimens is conducted by using non-isothermal elastoplastic damage constitutive model and two-dimensional plane stress finite elements [2]. During the experiment the displacement and temperature distribution on the specimens surface is measured by optical measuring system ARAMIS 4M and infrared thermography [1, 3]. This has enabled more precise calibration of material parameters in constitutive relations. In order to validate numerical model, an algorithm has been developed and implemented into the software script to automate the comparison of experimental and numerical data.
