“…When loaded to high filler concentrations, their dynamic properties become increasingly dominated by the particle phase, whereas the matrix itself seems to serve only as a binder for suspension purposes [12]. Such a phenomenon suggests that the static properties of a composite can be tuned by varying the polymeric matrix without hindering its dynamic performance.…”

Abstract. The present study investigates the complex multiscale dynamic response of particle-filled systems in an effort to link the bulk material behavior to strain-rate activated microstructures. These investigations involve multiphase systems consisting of micron-sized ceramic powders integrated within a siloxane elastomer to create flexible composites having varying inclusion properties. In particular, the effects of varying particle volume fraction, strength, and density are under investigation. The experimental investigation concerns the ballistic penetration of composite targets that are impacted by 16-grain blunt-nosed steel projectiles in the range of 200 -900 m s −1 . The results are compared to an analytical penetration model in order to shed light on the dominant penetration mechanisms and their relationship to the composite microstructure.

“…Since significantly developed by Kolsky [1] several decades ago, the split Hopkinson pressure bar (SHPB) technique has been widely used by many researchers to study the dynamic mechanics characteristic of a variety of materials, such as concrete [2], polymer [3], memory alloy [4] and even human bone [5] under high strain rate. Recently, the free Hopkinson pressure bar (FHPB) technique was introduced to evaluate the performance of accelerometers [6] and also extended to test the anti-overload characteristics of initiator or blasting cap under high-g loading by using the free Hopkinson pressure bar technique [7].…”

Based on the free Hopkinson pressure bar high-g loading technique, the pure cylindrical lead was mounted on the end section of the incident bar as a specimen to obtain the change law of the axial strain with the shape of acceleration pulses. Both the experimental tests without using pulse shaper and numerical simulations under sine-shaped acceleration pulses were performed and axial strain of the specimen was measured. Results revealed that the shape of acceleration pulse shows highly effect on the damage of the specimen. The axial strain of the specimen arises linearly with the increasing of the acceleration peaks whose durations are all 17μs; while, due to the complexity of plastic wave propagation, 135μs is a critical duration at which axial strain reaches to the maximum under the condition of different durations. The final axial strain of the specimen is determined by both the stress level and stress increment in every time step.
