“…Manganin stress gauges of type LM-SS-125CH-048 (longitudinal) and type J2M-SS-580SF-025 (lateral), manufactured by Vishay Micro-Measurements, allowed shock propagation to be monitored. Knowledge of flyer plate properties allowed calculation of key shock variables via the impedance matching technique [6], with gauge calibration following Rosenberg et al [7] for longitudinal gauges and Rosenberg et al [8,9] and Millett et al [10] for lateral gauges. …”

Abstract. Carbon fiber composites are becoming ever more important in the design and construction of vehicles for the aerospace industry. Such vehicles will be subjected to transient loading during their inservice lives. Consequently, it is important to know how carbon fiber composites behave while under shock loading. This study investigates the shock response of a tape wrapped carbon fiber composite with a phenolic resin matrix and with the carbon fiber weave angled perpendicular to the direction of impact. The Hugoniot equation of state was found to be linear and of the form U S =3.69+0.59u p . Periodic oscillations were observed on many of the traces, attributed to interactions between the various layers of the composite. Further, a Hugoniot elastic limit of 1.39 ± 0.19 GPa was found. Finally, embedded lateral stress gauges indicated that at low pressures (< 5 GPa), lateral stresses in the composite were comparable to what would be expected in the matrix material alone, e.g. the lateral behaviour was highly dependent on the phenolic resin.

“…Voltage-time data from the gages were converted to stress-time using the methods of Rosenberg and Partom, [38] with a modified analysis that does not require prior knowledge of the impact conditions. [39] In addition, in a very recent work, [40] we have shown that the geometry of the stress gage at low stresses can influence the final result and consequently must be accounted for.…”

The response of pure nickel (Ni), a binary Ni-60 at. pct cobalt (Co) alloy exhibiting a low stacking fault energy (SFE), and the ordered face-centered-cubic (fcc) alloy Ni-24Al-0.01B to shock loading has been studied using the technique of plate impact. Changes in the variation of mechanical properties with shock amplitude and pulse duration have been explained in terms of a shift from dislocation dominated to twin dominated plasticity in the case of the Ni-Co alloy and the increasing effect of brittle failure in the case of Ni 3 Al.

“…6 illustrates the calculation of the critical shear strength of the 2024 aluminum alloy under different preshocked states by self-consistent method. The critical shear strength can be obtained by following four steps: 16,26 (i) State 2 and state 4 are defined as maximum or minimum shear stress states at the reshock path or the release path because the Lagrangian wave velocity reduces to the bulk wave speed at those states; (ii) A tangent line can be drawn at the state 2 or state 4, and the extension of the tangent line can be made; (iii) The maximum stress point A or the minimum stress point B can be determined by the intersection point between the extending line and the vertical line passing the preshocked point; (iv) Finally, the critical shear strengths can be calculated by equation (7).…”

“…In the following years, the piezoresistive stress gauge (made of manganin or ytterbium) technique was also used as lateral stress transducers by Rosenberg et al, 6,7 Gupta et al, 8,9 Dai et al, 10 Winter et al 11 The calibration of the gauge is the focus of their researches. Since the lateral stresses in the shock-loaded solids are usually unknown, a simple calibration of lateral gauges, in terms of resistance changes vs. lateral stresses is practically impossible to achieve.…”

Articles you may be interested inCompressive strength measurements in aluminum for shock compression over the stress range of Journal of Applied Physics 98, 033524 (2005) A series of plate impact shock-reshock and shock-release experiments were conducted by using an one-stage light gas gun to determine the critical shear strength of the 2024 aluminum alloy under shock compression levels ranging from 0.66 to 3.05 GPa in the present study. In the experiments, a dual flyer plate assembly, i.e., the 2024 aluminum alloy flyer backed either by a brass plate or a PMMA plate, was utilized to produce reshock or release wave. The stress profiles of uniaxial plane strain wave propagation in the 2024 aluminum alloy sample under different pre-compressed states were measured by the embedded stress gauges. The stress-strain data at corresponding states were then calculated by a Lagrangian analysis method named as path line method. The critical shear strengths at different stress levels were finally obtained by self-consistent method. The results show that, at the low shock compression level (0.66 to 3.05 GPa), the critical shear strength of the 2024 aluminum alloy cannot be ignored and increases with the increasing longitudinal stress, which may be attributed to rate-dependence and/or pressure dependent yield behavior of the 2024 aluminum alloy.
