The dynamic-mechanical response of flexible polymer networks is studied in the framework of tube model, in the limit of small affine deformations, using the approach based on Rayleighian dissipation function. The dynamic complex modulus G∗(ω) is calculated from the analysis of a network strand relaxation to the new equilibrium conformation around the distorted primitive path. Chain equilibratio...

Soft structures with rationally designed architectures capable of large, nonlinear deformation present opportunities for unprecedented, highly tunable devices and machines. However, the highly dissipative nature of soft materials intrinsically limits or prevents certain functions, such as the propagation of mechanical signals. Here we present an architected soft system composed of elastomeric b...

Objectives: To evaluate the effects of one versus four weeks reactivation elastomeric chain on rate orthodontic tooth movement (OTM) and supporting structures.
 Methods: The 3rd maxillary premolars 8 male mongrel dogs were extracted. Custom made appliance was constructed so that 2nd allowed to slide bodily. An with calibrated force 150g attached hooks soldered tubes premolar’s crowns. samp...

BACKGROUND The present study was done to evaluate the dimensional stability and surface quality of Type IV gypsum casts retrieved from disinfected elastomeric impression materials. MATERIALS AND METHODS In an in vitro study contaminated impression material with known bacterial species was disinfected with disinfectants followed by culturing the swab sample to assess reduction in level of bact...
