C. Albertini et M. Montagnani, STUDY OF THE TRUE TENSILE STRESS-STRAIN DIAGRAM OF PLAIN CONCRETE WITH REAL SIZE AGGREGATE - NEED FOR AND DESIGN OF A LARGE HOPKINSON BAR BUNDLE, Journal de physique. IV, 4(C8), 1994, pp. 113-118
The idea is discussed of using two specular bundles of Hopkinson's bar
s for the experimental observation of the instantaneous distribution o
f stress and strain over the cross-section of large concrete specimens
with real size aggregate, subjected to high loading rates.
