“…Such error could result from the anisotropic strain rate dependency observed in the work of Breumier et al. [ 46 ] It could also result from errors on the plastic parameters that are not identified by the authors such as the interaction matrix. Indeed, gliding interactions tend to have less impact on the total plastic deformation when impacting along the [100] orientation when compared to impact along the [110] orientation as gliding systems are more heterogeneously activated in the latter case.…”

Instrumented single‐shot experiments provide crucial information of a material's response to impact events that can be used in shot‐peening modelling. However, no authors successfully used such test for constitutive model identification and validation as existing test rig generally cannot provide an accurate determination of the shot trajectory in three dimensions over a wide velocity range. In this work, a shot‐peening test rig that can propel single shot under the process conditions with a high aiming accuracy is presented. The test rig propels industrial shot by sudden pressurised gas release. A methodology to recover the propelled shot three‐dimensional trajectory within a 200‐μm accuracy using two high‐frequency cameras is developed in an open‐source in‐house code. The test rig can propel 0.5‐, 1.19‐ and 2.5‐mm‐diameter shot at velocity ranging from 0.8 to 143 m s−1 and can send several shots at the same position when using the largest shot diameter. Two potential applications of the set‐up are presented for (i) coefficient of restitution measurement with different shooting angles and velocities and (ii) crystal plasticity finite element model validation using the impact dent topology, the shot displacement curve and the crystal misorientation field under the dent.

“…Because the strain rate of SHPB test is not constant in the entire loading process, the representative strain rate is usually defined as the mean value of the strain rate over the loading period [19,20]. This definition of representative strain rate is adopted in this paper.…”

In-plane compression experiments are performed on 3D fine weave pierced C/C composite at a wide strain rate range of 0.0001/s-1000/s. The in-plane compressive failure mechanism of the composite at quasi-static and high strain rates is analyzed by a scanning electron microscope. The results show that the in-plane compressive modulus, maximum stress and the corresponding strain increase with increasing strain rate. The quasi-static in-plane compressive failure mode of the 3D fine weave pierced C/C composite is characterized by the shear failure at the angle of 45 • and the local buckling of the x-direction fiber bundles. In comparison, the high strain rate in-plane compression failure mode of the composite is characterized by the compressive fracture of the interlaminar matrix and the progressive compression failure of the x-direction fiber bundles. A strain-rate-dependent in-plane compressive constitutive model is proposed to predict the dynamic in-plane compressive response of the composite. The proposed constitutive model is verified by experimental data.

“…Though recently, the authors of this study reported the micromechanical properties of fused silica and 3D-printed polymer structures at strain rates up to 1000 s −1 using a piezobased testing platform [15,16]. There are also a small number of other recent key studies on copper micropillar compression conducted at strain rates up to 100 s −1 and nanoindentation of coarse-grained aluminium and nanocrystalline nickel performed at indentation strain rates up to 100 s −1 [17,18].…”

High strain rate micromechanical testing can assist researchers in elucidating complex deformation mechanisms in advanced material systems. In this work, the interactions of atomic-scale chemistry and strain rate in affecting the deformation response of a Zr-based metallic glass was studied by varying the concentration of oxygen dissolved into the local structure. Compression of micropillars over six decades of strain rate uncovered a remarkable reversal of the strain rate sensitivity from negative to positive above ~ 5 s−1 due to a delocalisation of shear transformation events within the pre-yield linear regime for both samples, while a higher oxygen content was found to generally decrease the strain rate sensitivity effect. It was also identified that the shear band propagation speed increases with the actuation speed, leading to a transition in the deformation behaviour from serrated to apparent non-serrated plastic flow at ~ 5 s−1.
