“…Materials which have been well-studied in the literature are silicone elastomers [13,66,151], plasticized PVC [152,153] and polyureas [39,40,72,[154][155][156][157][158][159] and polyurethanes [160][161][162]. The rate dependence of these materials depends strongly on the glass transition, and in particular whether this transition affects the room temperature response at strain rates of interest.…”

The mechanical properties of polymers are becoming increasingly important as they are used in structural applications, both on their own and as matrix materials for composites. It has long been known that these mechanical properties are dependent on strain rate, temperature, and pressure. In this paper, the methods for dynamic loading of polymers will be briefly reviewed. The high strain rate mechanical properties of several classes of polymers, i.e. glassy and rubbery amorphous polymers and semi-crystalline polymers will be reviewed. Additionally, time-temperature superposition for rate dependent large strain properties and pressure dependence in polymers will be discussed. Constitutive modeling and shock properties of polymers will not be discussed in this review.

“…Over the past 15 years, a wide range of investigations of the mechanical properties of polymer bonded explosives (PBXs), and their simulants (PBSs), under high rate deformation have been seen in literature [3,[16][17][18][19][20][21][22][23][24][25], often using Brazilian testing to study tensile behavior (e.g. [26,27]).…”

Characterizing the response of composite materials to high strain rate deformation is of great importance for a range of applications; however, the experiments required to do this are challenging. In order to be fully representative, specimens must be large, making it difficult to achieve mechanical equilibrium; furthermore diagnostic tools such as X-ray tomography and electron microscopy cannot be used on the required timescales of ca 10 ls. Many composites consist of a rate and temperature dependent polymer binder, with a filler that is independent of these parameters. In this paper, a simulation technique is applied, in which the high rate mechanical response of a composite is experimentally reproduced in low strain rate experiments by making use of the polymer time-temperature superposition principle. This is a novel application of time-temperature superposition to composite materials in order to experimentally replicate the high-rate response. In order to demonstrate this method on a model composite material, a particulate composite (polymer bonded sugar) and its binder are extensively characterized in compression, and the composite in indirect tension (Brazilian) tests, over a range of strain rates and temperatures. It is then shown that by reducing the temperature, low rate experiments can be performed which faithfully replicate the high rate data, opening up the opportunity for more extensive research programs combining mechanical testing and microstructural characterization of these materials.

“…However, within the field, only XCT has received any considerable attention [12,13]. It has been the authors own experience with XCT on highly filled PBXs that one of the biggest limitations arises from a lack of contrast between the PBX constituents due to their atomic similitude (in some cases exact), and their correspondingly very close attenuation coefficients for x-rays.…”

Abstract. A review of imaging techniques which can be used to acquire three dimensional data on polymer composite materials is presented. The techniques chosen utilise a variety of contrast forming mechanisms including x-ray, nuclear magnetic resonance and optical & electron microscopy. Discussion is illustrated with reference to a particular HMX based UK PBX. The achievable contrast and spatial resolutions are considered, with arguments relating to destructive and non-destructive methods of acquiring data. The eventual use of this work will be in computational modelling.
