Abstract

From the theoretical point of view, systems composed by masonry arches or vaults would require, during construction, the simultaneous activation of all structural elements in order to reach [...]

Abstract

This paper presents a continuum model for the simulation of the viscous effects and the long-term damage accumulation in masonry structures. The rheological model is based on a generalized Maxwell chain representation with a constitutive law utilizing a limited number of internal [...]

Abstract

The study and development of recycling techniques for pavements is an increasing activity in engineering nowadays. This research line demands a more [...]

Abstract

This study assesses five steps for Tank 241-AN-105 waste retrieval and subsequent pipeline transfer: 1. Remove supernatant liquid waste from AN-105 and transfer it through a pipeline with inline dilution with water (1st liquid waste transfer). 2. Add water (as a diluent) to Tank AN-105. [...]

Abstract

Viscosity is the property of fluids to oppose movement when a cutting effort is applied on them to convey them from one point to another. Heavy oil has a high viscosity greater than 1000 cP, which makes it difficult to transport. The present work shows a mathematical model for the [...]

Abstract

utomobile industry is one of the most developed industries in Ukraine and in the world today. The ever-increasing demand for transportation leads to an increase in demand for fuel, which in turn increases its deficit and value. Therefore, the high cost of traditional hydrocarbon fuels [...]

Abstract

Increased environmental awareness is driving the continuous search for new eco-friendly materials. Within the category of Wood Plastics Composites (WPC), a new "Green Composite" is proposed, whose matrix is a bio-polyethylene (bioPE) obtained from sugar cane and whose [...]
