Abstract The aim of this research was to provide values for different material properties considered in either traditional or more recent numerical silo design methods. Different samples granular agricultural materials commonly stored silos were tested. Common geotechnical devices have been used order make the replications easier. Based on these experiments it determined that not affected by test velocity, except case Poisson ratio. From a practical point view, velocity correlates well with...

The use of numerical methods in the design silos requires properties that describe behavior materials thatare commonly stored silos. Variations values these parameters can result risk failures this type ofstructure. Because lack existing data literature, goal research was to: (1) provide different testingmethods for determining properties, and (2) determine mechanical be used eithertraditional or more recent silo methods.

Abstract Grain, forage cereals and different types of flour are commonly stored in silos. Their behavior within these structures is mainly governed by their mechanical properties. Since advent, numerical methods have increasingly been used silo design. However, the results obtained using strongly depend on variables employed to define materials stored. literature provides little information required for modeling agricultural powdered materials, goals present work were to: i) provide values...

The loads generated inside agricultural silos under static and dynamic conditions depend on the mechanical properties of materials stored them. silo calculation methodologies are based these properties. Although it is known that moisture content greatly influences values reached by properties, just few studies have been conducted to determine present work determines angle internal friction, apparent cohesion, dilatancy specific weight wheat when subjected different contents. Direct shear...

Traditionally, the design of silos was carried out using classical theories. Hence, it is possible to find data on manygranular agricultural materials for all material properties considered in these Nevertheless, application ofnumerical methods silo relatively recent. With methods, new are needed, additionto ones theories, order estimate grain loads inside silos. As there a lack newparameters existing literature, goal this research provide values needed silodesign several granular materials....

The mechanical properties of the materials stored in agricultural silos determine loads they generate under static and dynamic conditions. present work describes wheat, maize wood pellets. Direct shear triaxial assay devices, oedometers (all commonly used geotechnical assays), were to these materials’ internal angle friction, Poisson’s ratio, Young’s modulus, apparent specific weight, etc. results for wheat similar those previously reported by other authors. For pellets, friction weight also...

Wood is poised to become a material of choice for future construction. When appropriately managed, it renewable with unique mechanical properties. Beyond its inherent sustainability, the use wood has crucial role in addressing climate change concerns due significantly lower energy consumption and emissions during manufacturing transportation, while simultaneously acting as carbon sink. Thus, there been growing demand hardwoods structural applications, including Castanea sativa Mill., focal...

It has been known for many years that highly dependent on moisture content material. However, to date there not studies focused its determination. goal this research is determination angle internal friction, apparent cohesion, dilatancy specific weight maize subjected...

The mechanical properties of agricultural materials influence not only the loads occurring inside silos, but also design several types post-harvest machinery. generated by these silos can be predicted with silo calculation methodologies from their properties. It has been known for many years that are highly dependent on moisture content material. However, to date, there studies focused its determination. goal this research is determination internal friction angle, apparent cohesion, angle...

Low-volume roads play an essential role in the development of rural areas Spain, yet most are a poor condition since hardly any money is designated for their upkeep. This work proposes management system Spanish low-volume road based on analysis present country's and networks, methodologies used inspection evaluation latter's (designed by authors), data from other countries. The proposed plan involves stages implantation, execution monitoring, each one with its own objectives. possible...

This study focuses on the friction characteristics of chestnut sawn timber (Castanea sativa Mill.) Spanish origin. The values both static and dynamic coefficients were determined, as this knowledge is interest for numerical simulation stress transmission in joints structures. Therefore, two sets tests carried out combining different orthotropic orientations. Firstly, timber-to-timber assessed to obtain applicable carpentry joints; secondly, timber-to-steel was also evaluated determine needed...

Lactose‐free (L –) formulas are recommended for infants with conditions affecting lactose digestion. Cows' milk protein‐based containing other carbohydrate sources most often used such infants. This study compared fat absorption and retention of nitrogen, calcium, phosphorus, magnesium in term fed either a L – or standard lactose‐containing (L+) bovine formula. Data from three single‐centre, double‐blind, randomized, parallel‐group metabolic balance studies were combined. After 4–7‐d...
