Analysis Frequencies of a Vibration-Type Structure Hall
Petrea, Ionel (Universitatea "Dunărea de Jos" din Galaţi, 2014)Its main purpose was to identify natural vibration frequencies for a warehouse type structure in order to avoid resonance phenomena of the structure. The analysis is performed using the finite element analysis module of ... -
Calibration and Reference Blocks Used in Nondestructive Ultrasound Examination, According to New European Union Requirements
Stanciu, Cristian; Petrea, Ionel (Universitatea "Dunărea de Jos" din Galați, 2006)Pursuant international standards such of the European ones, the nondestructive examinations have to be worked out by the most possible accuracy and repeatability, that allow the difference making between the admitted ... -
Experimental Researches on the Constitutive Equation of Concrete Steel with Superior Characteristics
Cănănău, Nicolae; Alexandru, Petrică; Gurău, Gheorghe; Petrea, Ionel (Universitatea "Dunărea de Jos" din Galați, 2007)The plastic deformation behavior is defined by the function of the deformation strength according to the strain, strain rate and temperature as the factor of the deformation process. The behavior law establishes by the ... -
Experimental Results at Modelling of the Flow and Deformation Fields at the Profiles Rolling
Cănănău, Nicolae; Petrea, Ionel (Universitatea "Dunărea de Jos" din Galați, 2006)This paper presents the results for modeling of the rolling process based at the deformable continuous medium mechanics, the theory of field lines. The rolling of the profiles and plates may be evaluated as the plane ... -
Melting-Casting Plant Using Vibrating of Melts in Order to Obtain Composite with Tehnological Utility
Bașliu, Vasile; Constantin, Ionuț; Istrate, Gina Genoveva; Petrea, Ionel (Universitatea "Dunărea de Jos" din Galați, 2010)This paper presents the obtaining of composites materials with technological utility through vibration technology. In order to obtain these composites, and plant was designed and manufactured. In order to show the ... -
Researches Regarding the Rolling of the Sinterized Metallic Powders Strips
Istrate, Sorin Miltiade; Petrea, Ionel (Universitatea "Dunarea de Jos" din Galați, 2005)This paper work is distinguishing the size modification of those two material layers gotten by the bimetallic strip rolling, joined by the sintering. The iron powders sediment was achieved on the steel strip backing. ... -
Static Ananysis of the Structure Type Tank Thermally
Petrea, Ionel (Universitatea "Dunărea de Jos" din Galați, 2013)This paper consider finite element analysis for structural analysis of a tank under thermal loadings. Geometric modeling is done in CATIA and for finite element analysis the author used FEA module in Catia. The aim is ...
