Analytical Simulations of Optimum Anisotropic Linear Viscoelastic Damping Properties
In a previous paper (Hilton & Yi 1992), a systematic study was undertaken to determine how shapes of relaxation–time functions affect damping characteristics of isotropic viscoelastic materials. The significant parameters were the instantaneous and fully relaxed moduli (Regions A and E on Fig. 1), the two “knees” (B and D), the central slope (C) and anisotropic shift functions. The sensitivity ...
متن کاملConstitutive model and wave equations for linear, viscoelastic, anisotropic media
Rocks are far from being isotropic and elastic. Such simplifications in modeling the seismic response of real geological structures may lead to misinterpretations, or even worse, to overlooking useful information. It is useless to develop highly accurate modeling algorithms or to naively use amplitude information in inversion processes if the stress-strain relations are based on simplified rheo...
متن کاملRelations between loss angles in isotropic linear viscoelastic materials
For the description of the mechanical behaviour of linear viscoelastic materials a number of characteristic material properties is in use. So the relaxation functions in shear, J(t), in extension, D(t), and in compression, B(t), describe the response of the material to a stepfunction H(t) in the corresponding stress. It can be shown theoretically that the relaxation functions are monotonically ...
متن کاملThe Symplectic Method in Polar Coordinates for Linear Viscoelastic Materials
In this study, the symplectic method is applied to a two-dimensional annular-sector viscoelastic domain under the polar coordinate system. By applying variable separation approach, all fundamental solutions are derived in analytical form. Furthermore, using the method of variable substitution, lateral conditions are transformed into finding a particular solution for the governing equations, and...
متن کامل[Viscoelastic behavior of alginate impression materials. Part 1. Linear viscoelasticity].
For taking accurate impressions, many material characteristics of the impression materials must be well understood. It is especially important to analyze the viscoelastic behavior of the impression materials. In our study, seven commercial alginate impression materials were used, and their linear viscoelasticity was measured using a creep meter (RE-3305, Yamaden Co.). The measurement condition ...
