Quasi-bifurcation and Imperfection-sensitivity of Cylindrical Shells under Pressures due to an Explosion
(Shahid Chamran University of Ahvaz, 2021-03)
The static and dynamic behavior of a horizontal cylindrical shell (as used to store fuels in tanks) is investigated in this work by means of computational modeling. Under a distributed pressure commonly used to model effects ...
A Comparative Wet Collapse Buckling Study for the Carcass Layer of Flexible Pipes
(ASME-AMER SOC MECHANICAL ENGNEW YORK, 2012-02)
When there is a failure on the external sheath of a flexible pipe, a high value of hydrostatic pressure is transferred to its internal plastic layer and consequently to its interlocked carcass, leading to the possibility ...
Análise da reversão do fundo de latas de alumínio para bebidas - Buckle
(Universidade Estadual Paulista (Unesp), 2015-02-13)
This work approaches the main methods of plastic deformation of metals, with a focus on the deep drawing process. The mechanical properties were evaluated with the tension tests. It is presented the aluminum alloys ...
Modelagem e análise numérica da estabilidade lateral com distorção de vigas mistas de aço e concreto
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2021-05-21)
The most rational behavior of steel-concrete composite beams occurs in the case of simply supported elements, in which the concrete is in compression and the steel profile in tension. However, in the continuous and ...
Análise numérica do fenômeno de flambagem em barras sob compressão centrada, formadas por materiais compostos, em seções transversais tipo “I” e tubular circular
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia MecânicaUTFPR, 2019-12-12)
Composite materials have emerged due to the need of developing stronger and lighter materials. They are applied in several engineering branches such as aeronautics, mechanics, naval, civil among others. The present work ...
Investigation of the Structural Fuse Concept
(2005-06-26)
Passive energy dissipation (PED devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this paper metallic dampers are defined to be structural fuses (SF) when ...
Floor Response of SDOF Systems with Metallic Structural Fuses
(2004-06-26)
The floor demands of Single-Degree-of-Freedom (SDOF) systems designed or retrofitted with metallic structural fuses are studied in this article. Floor velocity and acceleration are obtained and comparisons are made between ...
Seismic Response of Hybrid Systems with Metallic and Viscous Dampers
(2016-06-27)
Metallic dampers can enhance structural performance by reducing seismically induced lateral displacements, and by reducing inelastic behavior of beams and columns. Limiting story drift also indirectly allows for mitigation ...
Preferred and Avoided Temperatures of the Prawn Macrobrachium Acanthochirus (Crustacea, Palaemonidae)
(Universidad del Zulia, 2009)
