“…Therefore, reliable intermediate strain‐rate experimental techniques need to be developed to obtain experimental data. Recently, a hydraulic testing machine has been used to investigate the mechanical properties of materials, such as steel, polyuria, and HTPB propellant, at intermediate strain rates. In the present study, such a testing system is used.…”

Low, intermediate, and high strain rate compression testing (1.7 3 10 24 to 2500 s 21 ) of the hydroxyl-terminated polybutadiene (HTPB) propellant at room temperature, were performed using a universal testing machine, a hydraulic testing machine, and a split Hopkinson pressure bar (SHPB), respectively. Results show that the stress linearly increases with strain at each condition; the increasing trend of stress at a given strain with the logarithm of strain rate changes from a linear to an exponential form at 1 s 21 . By combining these characteristics, we propose a rate-dependent constitutive model which is a linearly elastic component as a base model, then multiplied by a rate-dependent component. Comparison of model with experimental data shows that it can characterize the compressive mechanical properties of HTPB propellant at strain rates from 1.7 3 10 24 to 2500 s 21 .

“…Therefore, it is significant to understand the hot tensile deformation behaviors and fracture characteristics of alloys for the optimal processing parameters. Recently, some researchers have studied the hot tensile deformation behaviors and fracture characteristics of different materials, such as CP-Ti [21], magnesium alloys [22,23], 42CrMo steel [24], GH4169 superalloy [25,26], Boron Steel [27], Al-Cu-Mg alloy [28], pure titanium [29], low carbon and micro alloyed steel [30].…”

“…The strain-rate influence on the plastic flow curve, described by the function ( ̇) , can be introduced in a multiplicative or additive way on the general strain hardening law. According to the coupling effects, four types of rate-dependent hardening model have been identified by Paul [32].…”

International audienceThe rate-dependent hardening behaviour of dual phase DP600 steel sheet is investigated by means of in-plane biaxial tensile tests, in an intermediate strain rate range (up to 20 s−1) and for large strains (up to 30% of equivalent plastic strain) at room temperature. The dynamic biaxial in-plane tensile tests are performed on a dedicated cruciform specimen shape previously developed and validated for large strains at quasi-static conditions. To perform dynamic biaxial tensile tests, a specific device is used to reduce oscillations on measure of forces. Based on these experiments, parameters of two phenomenological strain-rate hardening models (saturated and power law), are identified. Material parameters are obtained from an optimisation process, based on the finite element modelling of the biaxial test, by minimising differences between experimental and simulated principal strains at the specimen centre. A comparison of the strain hardening functions calibrated from both biaxial and uniaxial tensile tests under static and dynamic conditions are then proposed. Results show that the biaxial procedure developed in this work, associated with a specific shape of the cross specimen, are more efficient to determine the rate-dependent hardening behaviour for large strains than the conventional uniaxial tensile test. © 2016 Elsevier B.V
