The results of nonlinear seismic analysis of a five-story building composed of reinforced concrete walls are shown. PERFORM 3D [1] computational program was used for the [...]

At present a series of phenomenological models are used for the description of flow curves of viscoplastic materials. Their application for the given materials hitherto s [...]

An additive method enabling a direct determination of axial flow rate for viscous (power-law model) and viscoplastic (Vo adlo model) fluids in concentric annuli is presen [...]

A number of papers have aimed at an analytical solution of an axial annular flow of power-law fluids, especially a relation: volumetric flow rate vs. pressure gradient. N [...]

In food industry a back extrusion represents one of the cheapest and time-saving experimental methods how to determine rheological characteristics of the fluids studied. [...]

The aim of this contribution is to present an empirical model taking into account ageing of highly concentrated emulsions. This model enables smooth passage from modellin [...]

Almost all empirical models dealing with the flow curves of nonNewtonian fluids can be applied only in the case of monotonous course of these curves. Exceptionally it is [...]

The present contribution indicates that precisely the same situation as with the determination of the so-called yield stress of viscoplastic materials concerns also the v [...]

Abstrakt: The aim of this contribution is to propose a new phenomenological model enabling description of non-monotonicity of shear-viscosity function for rheologically c [...]
