SHPB Test of High-Strength Concrete Atlantis Press

The SHPB of 120 mm was used to investigate the dynamic mechanical behavior of the high-strength concrete under impact loading.To research the effect of different strength grade (54.82 MPa, 63.75 MPa, 84.00 MPa) and different strain rate (10 ~ 40 / s) for the dynamic mechanical properties of concrete, the results show that: It is feasible to research...

SHPB Test on High-Strength Concrete Semantic Scholar

By using the large size Hopkinson pressure bar with variable cross sections, split hopkinson bar tests have been made on two high strength concrete specimens, whose diameters are 72mm and 62mm respectively. The dynamic compression intention of concrete under variable strain rate, and the overall process curves of the stress strain obtained from the tests prove the strain rate sensitivity of ...

Fig. 4 shows the failure patterns of concrete specimens C40A-S3-1 and C40A-S1-3 recovered after the SHPB tests at low and high strain-rates. As illustrated in Fig. 4, the strain rate has great effect on the failure patterns of concrete.From the specimen still in large pieces at low strain-rate of 72 s −1, it was observed that the failure pattern of the SHPB specimen was vertical splitting of ...

ISSUES OF SHPB TEST ON CONCRETE-LIKE MATERIAL

The split Hopkinson pressure bar test is the major method in studying the dynamic properties of concrete-like materials. Firstly, we briefly reviewed the progresses of some issues of the SHPB test of concrete-like materials, i.e. the end friction effect, the aggregate effect, the temperature effect and the inertia effect. Secondly, some mechanism analyses of the inertial effects were performed ...

Response of high-strength concrete to dynamic compressive ...

01-10-2017  Heard et al. employed annular pulse shapers in SHPB tests of concrete materials to improve dynamic stress equilibrium in specimens and achieved constant strain rates. Their technique was applied to a self-consolidating high-strength concrete with a static strength of ∼80 MPa, to examine its dynamic response, and a significant increase in compressive strength with strain rate was observed.

Effect of maximum coarse aggregate size on dynamic ...

SHPB tests for mortar and concrete with various aggregate sizes were performed. • Heterogeneity was negligible with aggregate smaller than a third of specimen size. • Pure rate DIFs varied along with maximum aggregate size, but there was no tendency. • A guide to maximum aggregate sizes for SHPB test specimens was suggested.
