The paper investigates some continuity properties of pullback and exponential attractors the non-autonomous problem Form II Mindlin's strain gradient viscoelastic plate derived recently by Aouadi [2]. Under quite general assumptions on nonlinear damping sources terms, we establish existence uniqueness weak strong solutions. We prove in natural space energy, its upper semicontinuity with respect...

A novel analytical model development and simulation of melt-electrospinning process is presented. Unconstrained equations motion for the description a discretized melt-electrospun fiber are formulated using Kane's method. The motions spinneret collector plate also incorporated into kinematics formulation to simulate direct writing three-dimensional printing scenarios. Constraints describing vis...

The phenomenon of buckling in compression of an elastic inhomogeneous medium under initial stress is well known. It is illustrated by the instability of a longitudinally compressed ‘elastic plate embedded in a medium of lower rigidity. Under a critical load buckling appears suddenly in the form of a sinusoidal folding of a certain wave-length. Such sudden buckling ,will, of course, not occur in...

Introduction Over the past years, in order to anchor a prosthetic component to bone, different cements based on selfpolymerizing poly (methyl methacrylate) (PMMA) have been widely used as commercial synthetic biomaterials. The aim of this study was to evaluate the influence of a PMMA-based bone cement (Palamed® G40) on the viscoelastic behaviour of spongy bone from proximal human tibial epiphys...

We used a cone and plate rheometer to evaluate the mechanical properties of actin over a wide range of oscillation frequencies and shear rates. Remarkably, both filamentous and nonfilamentous actin behaved as viscoelastic solids in both oscillatory and shear type experiments, providing that they were given ample time to equilibrate. Actin was purified by gel filtration from rabbit skeletal musc...

The compressive high strain-rate behavior of polymeric Kelvin lattice structures with rod-based or plate-based unit cells was investigated through experimental techniques and finite element simulations. Polymeric 5x5x5 cell geometries were manufactured on the millimeter scale using vat polymerization additive manufacturing tested at low (0.001/s) (1000/s) strain-rates. High experiments performe...
