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.
The objective of this work is to perform an analysis pressure distributions in grain silos for both the discharge and static conditions with eccentric outlets. To end, commercial ANSYS program, based on finite-element method employed. In paper, results are presented a silo height 10.5 m (cylinder 8 m, base cone 2.5 m), radius 3 outlet 0.5 m. Outlet eccentricity ranged from 0% (central outlet) 100% (maximally outlet, tangential cylinder). Based results, paper proposes new methods analyzing...
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 design of engineering high value-added products and timber structures analysis requires reliable elastic characteristics related to a theoretical model that describes the behavior wood material.The present research focuses on determining constants Eucalyptus globulus Labill., which allow their implementation as input parameters in any numerical model.The great potential this species for novel structural applications was considered due its superior mechanical properties.Two different...
Eucalyptus globulus Labill stands out as one of the hardwood species produced in Europe with prominent mechanical properties, which is undergoing a growing interest extending added value. The development engineered wood products this and its application timber structures involving numerical finite element simulations requires knowledge properties for different orthotropic material directions. aim present study to determine main E. from small clear specimens, necessary models. work provides...
Elastic timber gridshells are lightweight structures whose stiffness is highly dependent on multiple factors, such as boundary conditions and the semi-rigidity eccentricity of joints. Their structural analysis requires calibrated numerical models that incorporate all aspects influencing stiffness. Unfortunately, very little research experimentally verified can be found. This paper focuses behaviour a novel concept triaxial elastic long-gridshells supported only their short sides, called by...
The influence of hopper eccentricity on silo discharge has always concerned researchers. Eccentric brings about asymmetries in the distribution normal pressures, values which are not known with precision. This study presents a three-dimensional model dynamic an eccentric hopper, considering Drucker-Prager plasticity for behavior stored material. results obtained different eccentricities reveal that pressures decrease along generatrix above outlet, as compared to opposite side. An increase...
The objective of this paper is to develop a twodimensional numerical model simulate the response Scots pine (Pinus sylvestris L.) defect free timber members in order predict behaviour these when subjected external forces. For purpose, data mechanical properties were obtained by performing experimental tests on specimens. We determined stresses and deformations beams elastic-plastic plastic phases. In addition, we developed finite element software that considered orthotropic nature timber,...
