A viscosity overshoot of fibers filled in a polymer melt under shear flow is much tougher to predict via the existing constitutive equations suspension rheology viscous media, owing effect fiber orientation on viscoelastic behavior. The WMT-X (White–Metzner model eXtended by Tseng) fluid coupled with typical Dinh–Armstrong model, known as suspended proposed herein. primary procedure involves ve...

We address the homogenisation of a linear viscoelastic and hierarchical composite material in one-dimensional (1D) framework via three-scale asymptotic method. consider family heterogeneous problems with periodic, rapidly-oscillating piece-wise coefficients that model structure two levels organisation. Here, we assume continuity contact conditions at interfaces among constituents set straightfo...

The hydromagnetic instability of the plane interface between two uniform, superposed and streaming Rivlin-Ericksen viscoelastic fluids through porous medium is considered. The case of two uniform streaming fluids separated by a horizontal boundary is studied. It is observed, for the special case where perturbations in the direction and transverse direction of streaming are ignored, that the sys...

Finite propagation speed properties in mathematical elastic and viscoelastic models are fundamental in many applications where the data exhibits propagating fronts. We note particularly that this property is observed in biomechanical imaging of tissue, in particular in the supersonic imaging experiment, and also in geophysics and ocean acoustics. With these applications in mind, noting that the...

This paper characterized bovine extraocular muscles (EOMs) using creep, which represents long-term stretching induced by a constant force. After preliminary optimization of testing conditions, 20 fresh EOM samples were subjected to four different loading rates of 1.67, 3.33, 8.33, and 16.67%/s, after which creep was observed for 1,500 s. A published quasilinear viscoelastic (QLV) relaxation fun...
