“…The challenges associated True Strain Fig. 5 Representative compressive stress-strain curves for a PMMA [128], b PC [19], c PVC [138], and d epoxy [74] across a range of strain rates with these elastomers are similar to those experienced when characterizing many biological materials, giving further motivation to the development of suitable experimental techniques.…”

“…For polymeric materials, these foil gauges can result in transmitted signals that cannot be distinguished from the noise. Increased sensitivity semiconductor strain gauges, which have a gauge factor *140 can be used to enable accurate measurement of small transmitted signals [74]. Additionally, piezoelectric gauges, such as x-cut quartz or lead zirconium titanate (PZT), can be placed in the experiment to provide enhanced sensitivity or to directly measure input and output forces [62][63][64]75].…”

“…There are several glassy polymers that have been extensively studied at high strain rate in the literature, including polymethylmethacrylate (PMMA) [16,95,100,[123][124][125][126][127][128][129][130][131][132], polycarbonate (PC) [15, 18-20, 100, 110, 124, 126, 127, 133-136], polyvinylchloride (PVC) [137,138] and varying classes of epoxy [23,74,[139][140][141]. The large number of studies on a ''single'' material indicates that it is critical to understand the pedigree of the polymer being tested, including processing history and storage.…”

“…6a, and epoxy [74] where experiments are conducted at every decade of strain rate using novel hydraulic loading devices capable of testing the intermediate rate regime reduced the uncertainty associated with the third reason described above. Typically, the increase in strain rate sensitivity in glassy polymers is attributed to activation of particular molecular mobility, often due to side chain motion or ring flips called the b-transition.…”

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.

Compressive mechanical properties of HTPB propellant at low, intermediate, and high strain rates

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 .

Visco‐elasto‐plastic constitutive model of adhesives under uniaxial compression in a range of strain rates

Determining the constitutive model of adhesives enables the prediction of the mechanical response of hybrid structures in which the adhesive is used. In this study, the stress-strain behavior of a two-component structural adhesive was first measured in uniaxial compression experiments at the strain rates ranging from 0.001 to 2600 s −1 for developing a constitutive model. It was found that the compressive response, including elastic modulus, yield strength, and plastic flow stress, is substantially influenced by the strain rate. In plastic deformation, the strain rate sensitivity is not constant but varies with the rate; moreover, strain softening and hardening dominate the plastic deformation at low and high strains, respectively. A visco-elasto-plastic constitutive model was then proposed for the adhesive, integrating the strain rate sensitivity that was quantified by empirical equations. The model which was validated can reliably represent the strain rate dependent compressive behavior of the adhesive.
