Nonlinear Viscoelastic Constitutive Relations and Nonlinear Viscoelastic Wave Propagation for Polymnonlinear viscoelastic waves mainly depend on the effective nonlinearity and the high frequency relaxation time ... An “effective influence distance/time” is defined to characterize the wave propagation range where .. dominates the impact relaxation process.Isolate 发表于 2025-3-31 15:45:10
Dynamic Measurement of Elastic Moduli for Composite Materials Using Disk Specimens,btained with only one specimen and one test apparatus. We tried to measure elastic moduli for a carbon fiber/epoxy composite material. As a result, it was found that the orthotropic elastic moduli .., .., .. could be measured easily within acceptable accuracy. but this method was suitable for measuring the Poisson’s ratio ...atrophy 发表于 2025-3-31 21:00:47

Joan Rosselló-Geli,Miquel Grimalt-Gelaberty. Here it is argued that the preference for a constant velocity is in accordance with a perception of the process region as a continuum at very high crack velocities, a consequence of the lost significance of an intrinsic length parameter.
