    A quasi-lumped model for the peripheral distortion of the arterial pulse by Panagiotes A. Voltairas, Antonios Charalambopoulos, Dimitrios I. Fotiadis, Lambros K. Michalis

    Published 2011-11-01
    “…It emanates from a generalized Bernoulli's equation for an an-harmonic, linear, viscoelastic, Maxwell fluid flow in a linear, viscoelastic, Kelvin-Voigt, thin, cylindrical vessel. We report that close to the heart, convection effects related to the change in the magnitude of the velocity of blood dominate the alteration of the shape of the pressure pulse, while at remote sites of the vascular tree, convection of vorticity, related to the change in the direction of the velocity of blood with respect to a mean axial flow, prevails. …”

    (In)stability of symbiotic vortex-bright soliton in holographic immiscible binary superfluids by Yu-Ping An, Li Li

    Published 2025-02-01
    “…Moreover, for giant symbiotic vortex-bright soliton structures with large winding numbers, the vortex splitting instability might be rooted in the Kelvin-Helmholtz instability. We also show that the second component in the vortex core could act as a stabilizer so as to suppress or even prevent vortex splitting instability. …”

    Influence of density of a polyurethane microcellular elastomer foam on its compressive energy absorption and time-dependent behavior by Julen Cortazar-Noguerol, Fernando Cortés, María Jesús Elejabarrieta

    Published 2025-01-01
    “…To obtain it, creep experimental data is gathered and converted to relaxation through the convolution relationship between these two properties by means of Maxwell and Kelvin generalized models. The results indicate increased stiffness and longer relaxation times for higher-density PUMEs, suggesting slower responses and lower deformations under the same load. …”

    An Updated Analytical Structural Pounding Force Model Based on Viscoelasticity of Materials by Qichao Xue, Chunwei Zhang, Jian He, Guangping Zou, Jingcai Zhang

    Published 2016-01-01
    “…Based on the summary of existing pounding force analytical models, an updated pounding force analysis method is proposed by introducing viscoelastic constitutive model and contact mechanics method. Traditional Kelvin viscoelastic pounding force model can be expanded to 3-parameter linear viscoelastic model by separating classic pounding model parameters into geometry parameters and viscoelastic material parameters. …”
