    From the experiments it was found that there is a significant enhancement in tensile strength with increasing strain-rates. The dynamic tests on steel FRC with the smaller loading rate (50 s 1 ) showed a strength similar to the one measured from static tests; however, for increasing loading rates, a remarkable decrease of post-peak strength and ductility occurs.

    The tensile behaviour (strain rate range between 14.3 s-1 and 214.8 s-1) was investigated by Wu et al. who conducted a series of spalling tests on UHPFRC specimens with three fibre volume contents (0%, 1%, 2%) and two types (micro-straight, hooked) of steel fibres. They observed high strain rate sensitivity for dynamic tensile behaviour, in particular for the matrix.

    The tests were carried out by using a Modified Hopkinson Bar apparatus on fibre reinforced concrete notched-specimens under three different strain-rates 50, 100, and 200 s-1. From the experiments it was found that there is a significant enhancement in tensile strength with increasing strain-rates.

  12. THE EFFECT OF STRAIN RATE ON TENSILE PROPERTIES

    Data quality of high strain rate testing is improved by applying strain gauge in grip section and DIC technique. Strain rate has little effect on uniform elongation and total elongation for Advanced High Strength Steels (AHSS) such as DP590 and DP780. In agreement with existing data, the tensile strength increases with strain rate.

    High Strain Rate Testing. MTS offers all the technology required to conduct accurate and repeatable high strain rate tests, including load frames capable of applying forces from 5 to 500 kN (1,100 to 110,000 lbf) and achieving velocities from 1 to 21 m/sec (39 to 830 in./sec). In

  17. The Strain Rate Effect : Plastics Technology

    We can observe this behavior using a lower strain-rate test such as a tensile test. Tensile tests apply stress over a significantly longer time scale than impact tests. Instead of a few millisec, tensile tests can last for 30 to 300 sec. But within this longer time envelope we can vary the strain rate by pulling the sample at different rates.
