VISCOELASTIC CHARACTERIZATION OF THE TEMPORAL STRAIN BEHAVIOR OF BIOMIMETIC MATERIALS IN A CREEP TEST CONFIGURATION.

摘要

To develop a creep test method designed to extract viscoelastic parameters from a specimen through the viscoelastic characterization of synthetic foam materials suffused in viscous liquids. Synthetic biphasic specimens represent an effective tool in the ultrasonic characterization of viscoelastic behavior, which allows evaluation of specific viscoelastic behavior at low cost. Poroelastic mechanisms are expected to be related to the material properties of the matrix, pore size and capillarity effects of the liquid suffusing the elastic matrix.
