Mechanical Characterization at Intermediate Strain Rates for Rate Effects on an Epoxy Syntactic Foam

International Journal of Mechanical Sciences, 2007
Abstract An intermediate strain-rate mechanical testing technique was developed through proper modifications of a hydraulically driven loading frame (MTS 810) and a split Hopkinson pressure bar (SHPB). The modified MTS and SHPB were used to obtain valid stress–strain data for an epoxy syntactic foam at intermediate strain rates in the order from 10 ...

Tensile Properties of Sheet Metals at Intermediate Strain Rates with Pre-Strain

steel research international, 2015
This paper investigates the tensile properties of sheet metals at intermediate strain rates in relation to the pre-strain history induced by the fabrication process. Sheet metals such as SPCEN(DDQ), EZNCD(DQ), SPCC(CQ), SPRC340R, and SPRC440E were selected with the pre-strain of 2, 5, and 10% by tensile elongation with static tensile test machine ...

Experimental Study of Tensile Properties of PMMA at Intermediate Strain Rate

Materials Letters, 2004
Abstract Tensile tests of polymethylmethacrylate (PMMA) at quasi-static loading conditions and at intermediate strain rates were performed on MTS810 materials test system and on a self-developed intermediate strain rate materials testing apparatus, respectively.

Plastic deformation of austenitic iron at intermediate strain rates

Metallurgical Transactions A, 1975
The plastic deformation of austenitic iron, represented by a zone-refined iron, an electrolytic iron, an Fe−0.05 C alloy, and an Fe−5.2 Mn alloy, has been documented for the temperature range 950 to 1350°C (1740 to 2460°F) and the strain-rate range 2.8 × 10−5 to 2.3 × 10−2 s−1.

Infrared Thermography for Material Characterization at Intermediate Strain Rates

2018
The presented activity consist in the measurement of the self-heating field during testing of a metallic material from quasi-static to intermediate strain rates (10−2 s−1–100 s−1). It is expected that for these strain-rates the self-heating process will be between the isothermal and adiabatic domains.

Energy consumption in rock fragmentation at intermediate strain rate

Journal of Central South University of Technology, 2009
In order to determine the relationship among energy consumption of rock and its fragmentation, dynamic strength and strain rate, granite, sandstone and limestone specimens were chosen and tested on large-diameter split Hopkinson pressure bar (SHPB) equipment with half-sine waveform loading at the strain rates ranging from 40 to 150 s−1.

A HYBRID TECHNIQUE FOR COMPRESSION TESTING AT INTERMEDIATE STRAIN RATES

Experimental Techniques, 1996
It is difficult to obtain accurate load information at strain rates on the order of 102 s−1 using a quartz load cell. We have developed a hybrid apparatus which combines the loading capability of a hydraulic test machine with the load-measurement technique of the Hopkinson bar.

The micromechanics‐based rate‐dependent constitutive model of flawed rocks at intermediate strain rate

Fatigue & Fracture of Engineering Materials & Structures, 2022
AbstractIn the previous works conducted by Zhou and Yang, the deformation induced by wing crack coalescence was not investigated. In this paper, a novel micromechanics‐based rate‐dependent constitutive model is proposed to investigate the effect of wing crack coalescence on the mechanical properties of rocks at intermediate strain rate.

Strain rate dependence of the yield stress and strain hardening rate of a single crystal superalloy at intermediate temperature

Materials Science and Engineering: A, 2015
Abstract The effect of temperature and strain rate on the yield stress and deformation mechanism of the DD6 single crystal is investigated. The results show that the strain rate has very limited effect on the yield stress and strain hardening rate at 873 K, but has strong effect on both properties at 1073 K. The situation at 873 K is similar with the
