RISAnalysis of Tubular Connections Using a Thin Cylinder Approximation—Part II
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The results from Part I of this two-part study are used to predict the performance of threaded connections, in particular API round thread connections. The effects of inelastic deformation, ...
Analysis of Tubular Connections Using a Thin Cylinder Approximation—Part I
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the first part of this two-part study, approximate equations for determining the stress state in an interference fit connection are derived. The relations presented are based on a thin ...
Collapse of Oil Well Casing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with the theoretical study of the collapse of oil well casing under various loading conditions. The analysis is based on a model of a cylindrical shell of infinite ...
Application of Strain Space Plasticity Theory to Surface Strain Gage Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Taking strain as the independent variable, the strain space plasticity theory introduced by Naghdi and Trapp is applied to the problem of interpreting strain gage readings for load paths that ...
Collapse of Oil Well Casing With Ovality
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear response and eventual collapse of an initially imperfect cross section of a cylinder of infinite length is analyzed. The cylinder is loaded by external pressure and axial load ...
Collapse of Imperfect Tubulars
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear response and eventual collapse of a cylinder loaded by resultant external pressure and axial load is analyzed. The cross-sectional description of the cylinder is sufficiently general ...
The Effect of Length: Diameter Ratio on Collapse of Casing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an analysis of the cross-sectional collapse of a cylinder of finite length loaded simultaneously by an axial tension (which may be zero) and external pressure. The calculation ...
A Finite Element Analysis of Collapse of Perforated Casing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to report the results of finite element analyses of the collapse of perforated casing. In the study, both inline (0-deg phasing) and staggered (90-deg phasing) ...
Investigation of API 8 Round Casing Connection Performance—Part II: Stresses and Criteria
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Comparison of stresses in Part I showed that the APILT&C 8 Round threaded casing connection could be accurately analyzed with finite element methods, with models that both included and ...
Investigation of API 8 Round Casing Connection Performance—Part III: Sealability and Torque
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of the API LT&C 8 Round casing connection is investigated using 7-in.-29-lb/ft pipe size. Part I showed that the finite element method was applicable for analysis using both ...
