Effect of UV Exposure on Mechanical Properties of POSS Reinforced Epoxy Nanocomposites,of the neat epoxy and epoxy/POSS nanocomposite has been studied using nanoindentation technique. Elastic modulus of the polymer systems are determined using modified Oliver–Pharr method taking creep rate into account. Creep compliance properties of the studied systems are determined by fitting a sta

Overcoming Challenges in Material Characterization of Polymers at Intermediate Strain Rates,as nonlinear viscoelastic–viscoplastic. Physical testing at intermediate strain rates creates many challenges because the measurements are susceptible to distortion due to factors including: test specimen variations, fixtures, hydraulic actuator control, instrumentation complexity, data acquisition,

Summary and Concluding Remarks,luated for performance versus actuators of increasing transverse curvature. Digital image correlation was implemented to quantify the out-of-plane deflection of the unimorph composite actuators (UCAs) during the actuation cycle. Experimental results indicate that an actuator with transverse curvatur

Furthermore, it was found that the yield point varied linearly with the logarithm of strain rate. A general three-dimensional elasto-viscoplastic model was formulated in

Additional experiments were designed to quantify the effects of stress relaxation and reloading. The experimental techniques developed and result
