The objective of this research is to establish structure-property relationships for macromolecules bearing reversibly associating side-groups. In previous studies we demonstrated shape-memory behavior for elastomer networks bearing strong ureidopyrimidinone (UPy) hydrogen-bonding side-groups. However, relationships between the underlying viscoelastic behavior and side-group features such as hyd...

In reconstructive surgery human bone defects are sometimes filled with the use of the impaction bone grafting technique. Currently different types of biomaterial particles are being developed as bone-substitute materials. Before these biomaterials can be applied their mechanical and biological behavior should be characterized. In this study the time-dependent mechanical behavior of biomaterial ...

this paper is concerned with the surface and small scale effects on transverse vibration of a viscoelastic single-layered graphene sheet (slgs) subjected to an in-plane magnetic field. the slgs is surrounded by an elastic medium which is simulated as visco-pasternak foundation. in order to investigate the small scale effects, the nonlocal elasticity theory is employed due to its simplicity and ...

Accurate joint models require the ability to predict soft tissue behavior. This study evaluates the ability of constitutive equations to predict the nonlinear and viscoelastic behavior of tendon and ligament during stress relaxation testing in a porcine model. Three constitutive equations are compared in their ability to model relaxation, recovery and reloading of tissues. Quasi-linear viscoela...

We perform micro-rheological experiments with a colloidal bead driven through viscoelastic worm-like micellar fluid and observe two distinctive shear thinning regimes, each of them displaying Newtonian-like plateau. The behavior at larger velocities is in qualitative agreement macroscopic rheological experiments. second process, observed Weissenberg numbers as small few percent, appears to have...
