Size effect on tensile impact mechanical properties and fracture process of plain concrete
In order to study the mechanical behaviour of plain concrete at high strain rates a new experimental methodology has been developed. This new technique concerns the tensile behaviour of concrete and recommends a development of the well known Hopkinson's bar technique. This paper describes the experiment and its capability of measuring the mechanical properties and the fracture process of plain concrete with large size aggregate under high loading rate and compares with those obtained from microconcrete having aggregate size of 5 mm to 10 mm. A strain rate dependent model for concrete under dynamic loading is also presented.
