Fatigue experiments on adhesively connected pultruded profiles were performed in a laboratory environment. The first objective was to determine if fatigue limits exist and if so, how their magnitude is compared to real shear stress amplitudes in GFRP bridg ...
In this paper, order one finite elements together with Galerkin least-squares (GLS) methods are used for solving a three-held Stokes problem arising from the numerical study of viscoelastic hows. Stability and convergence results are established, even when ...
The present paper discusses the uniqueflow behavior in a new type of extruder. The extruder design is based on a hollow conical assembly of static (stators) and rotating (rotor) parts. Extrusion is achieved from each side of the rotor to provide a two-laye ...
Dispersive mixing of high viscosity ratio blends was studied in a converging flow using a capillary rheometer equipped with dies having different entry profiles. Three inhomogeneous bimodal polyolefin blends, with stress-dependent viscosity ratios ranging ...
When the effects of physical aging below Tg are erased, the rheological response of a series of aliphatic hyperbranched polyesters is Newtonian and the melt viscosity scales roughly linearly with Mw at high Mw, indicating entanglement to be absent. The rhe ...
