Common root causes in recent failures of cranes
(Elsevier, 2014-02)
Catastrophic failure of cranes is a potentially very dangerous event and has often fatal consequences. The failures of two cranes are discussed in this study. Both cranes have different designs, but common root causes have ...
Análise estrutural do chassi de um transbordo canavieiro
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia MecânicaUTFPR, 2017-06-23)
The purpose of this study is to analyze the sugarcane market in Brazil, showing a brief history of its development and application. Also, this paper introduces a structural analysis of a sugarcane wagon project from the ...
Critérios para análise de viabilidade para manutenção preditiva em válvulas de controle em indústrias de processo
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrônica, 2013-11-05)
The objective of this work is the definition of criteria for evaluating the feasibility of implementation of predictive maintenance techniques for control valves in process industries. Furthermore, this work brings a view ...
Distortional buckling of simple lipped channel in bending results of the experimental analysis versus direct strength methods
(2006-12-01)
Cold-formed steel members are subject to failure caused by buckling, normally under loads smaller than those corresponding to partial or total yielding of the cross section. The buckling of members in bending can be ...
Artificial Immune Systems Applied to the Analysis of Structural Integrity of a Building
(Trans Tech Publications Ltd, 2014-01-01)
This paper presents the application of artificial immune systems for analysis of the structural integrity of a building. Inspired by a biological process, it uses the negative selection algorithm to perform the identification ...
Quantification of parametric uncertainties effects in structural failure criteria
(Universidade Estadual Paulista (Unesp), 2019-02-04)
Critérios de falhas realizam a predição de circunstâncias nas quais materiais sólidos estão sobre ação de carregamentos externos. As teorias de falhas são conhecidas como diferentes critérios de falhas, como von Mises e ...
A comparison of deterministic, reliability-based and risk-based structural optimization under uncertainty
(ELSEVIER SCI LTDOXFORD, 2012)
In this paper, the effects of uncertainty and expected costs of failure on optimum structural design are investigated, by comparing three distinct formulations of structural optimization problems. Deterministic Design ...
Failure prediction analysis for polyethylene flawed pipes
(Pergamon-Elsevier Science Ltd, 2002-12-24)
Through this paper limit load analysis and the EPRI/GE procedure were applied to predict instability conditions for medium density polyethylene flawed pipes. Predicted values for internally pressurized cylinders with axial ...
