Abstract
This paper presents a comparison between mechanical compressive and tensile properties of S355 structural (mild) steel in a wide range of strain rates. A split Hopkinson pressure bar apparatus is used to investigate the dynamic compressive behaviour at high strain rates (740--5880 s‚àí1). A hydro-pneumatic machine (5--25 s‚àí1) and a modified split Hopkinson tensile bar apparatus (300--850 s^-1) are used to study the strain rate sensitivity under dynamic tension. Quasi-static tensile and compressive tests are conducted on a universal electromechanical testing machine. The model parameters of two commonly used constitutive equations (Johnson--Cook and Cowper--Symonds) are also compared, separately for each model during compression and tension deformations.
