چکیده انگلیسی
The glass interface effect on dynamic tensile response of a soft polyurethane elastomeric polymer material has been investigated by subjecting a glass-polymer system of this polymer material matrix embedded a single 3Â mm-diameter glass particle to impact loading in a split Hopkinson tension bar (SHTB) setup. The characteristics of the dynamic stress-strain response of the glass-polymer system have been determined. Yield stress and maximum stress show strain rate dependency according to a power-law function. Glass interface effects on dynamic properties were studied quantitatively at different strain rates. The debonding deformation behaviour accompanied by cavitation and necking has been carefully analysed. Damage mechanisms were explored in order to understand crack initiation and propagation at the glass-polymer interface and inside the polymer matrix. This work is of significance in order to evaluate a transparent impact-resistant device of a soft polyurethane elastomeric polymer material backed by the rigid glass, to develop a particle-polymer system for propellant and to calibrate computational models for designing an advanced rigid-particle-modified composite material system for protective applications.
