About the Parametric Modelling of the Protective structure Included in a Tractor Cabin in Order to Study its Protective Capability Using the Finite Element Method
Dumitrache, Petru (Universitatea "Dunărea de Jos" din Galați, 2014)The objective of the paper is the highlighting of the main aspects that are considered in parametric modelling of the protective structures included in a tractor cabin in order to study its protective capability, using ... -
Considerations on the Simplified Numerical Simulation of the Bus Lateral Rollover
Dumitrache, Petru (Universitatea "Dunărea de Jos" din Galați, 2013-10-01)The numerical simulation using finite element method, of the behavior of buses in case of lateral rollover, requires significant hardware resources and can lead to the numerical models whose resolution may take prohibitively ... -
On the Control of the Element Finite Meshes with Dimension in Arithmetic Progression
Dumitrache, Petru (Universitatea "Dunărea de Jos" din Galați, 2012)The purpose of this article is to present the formulae for calculating the parameters defining the finite element meshes with variable dimensions in arithmetical progression along some user defined paths within the ... -
On the Linear Elastic Deformations for plane curved Bems in their Plan Loded, Using the Finite Element Method
Dumitrache, Petru; Potîrniche, Aurora (Universitatea "Dunărea de Jos" din Galaţi, 2006)The study want to make a comparison between tho calculus methods of the linear elastic deformations for plane curved beams in their plan loaded. The results obtained with the finite element analysis have some important ... -
On the Stresses and Deflections Calculus in Bending the Cylindrical Naturally Twisted Bars, with Constant
Dumitrache, Petru (Universitatea "Dunărea de Jos" din Galați, 2011)The present paper deals with some aspects of the stresses and deflections calculus in case of the cylindrical, naturally twisted bars, with constant pitch, on the basis of assumptions on the linear-elastic behavior of ... -
Regarding the Efficiency of the Decelaration Through Impedance Coiling of the Hydraulic Cylinders
Hauk, Niculai; Dumitrache, Petru (Universitatea "Dunarea de Jos" din Galați, 2004)The paper present a point of view sustained by calculations about the efficiency of the deceleration system by impedance coiling of the hydraulic cylinders. It is shown that the simple presentation of the impedance ... -
Shear Stresses in Beams with Variable Cross Section, Subjected to Non-Uniform Bending
Dumitrache, Petru (Universitatea "Dunărea de Jos" din Galați, 2012)The goal of this paper is to present a generalization of the Juravski formula (appropriate for the beams with constant cross section, subjected to non-uniform bending), for the beams with variable cross section. In the ... -
A Solution to a Deflection Beam Problem
Dumitrache, Petru; Hauk, Niculai; Goanță, Adrian Mihail (Universitatea "Dunărea de Jos" din Galați, 2004)The present paper shows how the minimal total potential energy principle it is used for elastic systems in the case of the determination of the linearelastic displacements which determines the beams bending. Qualitative aspects ... -
Some Aspects of the Calculation of Beams Loaded with Mobile Forces with Variable Intensity
Dumitrache, Petru (Universitatea "Dunărea de Jos" din Galați, 2010)In this article is presented the case of the beams which are loaded by mobile forces with variable intensity along the beam. In this context, after calculus assumptions and calculus model are presented, necessary formulas ...
