Objective
Measurement of the true energy absorption capability of the unit material volume during fracture of brittle materials (plain concrete). This data is fundamental for structural analysis of failure during service, earthquake, impact loading (see annexed report). The measurement will be performed using concrete with real size aggregate because the data from microconcrete are not transferable to real structures.
Progress to end 1991
Conceptual design of the uniaxial Hopkinson's bar bundle (see annexed report). Contacts with ENEL and ENEA which intend to apply this methodology to concrete with real size aggregate and fiber reinforced concrete.
Detailed description of work foreseen in 1992 (expected results)
Construction of the Hopkinson's bar bundle and verification of its performances. Installation of the bar bundle in the LDTF in order to measure the true stress-strain diagramme of concrete with real size aggregate (specimen of 20 x 20 x 20 cm) during fracture by crack propagation, at low, medium and high strain rate.
Short description of evolution of work in 1993
Continuation of the measurements in collaboration with ENEL and ENEA. Design of a biaxial version of the equipment in order to study the influence of loading direction.
