Bending instabilities of elastic tubes
(2002)The present paper examines instabilities of long thin elastic tubes. Both initially straight and initially bent tubes are analyzed under in-plane bending. Tube response, a combination of ovalization instability and bifurcation ... -
Buckling and post-buckling of long pressurized elastic thin-walled tubes under in-plane bending
(2006)The present paper focuses on the structural stability of long uniformly pressurized thin elastic tubular shells subjected to in-plane bending. Using a special-purpose non-linear finite element technique, bifurcation on the ... -
Buckling of High-Strength Steel Cylinders Under Cyclic Bending in the Inelastic Range
(2014)The present paper examines the structural behavior of elongated steel hollow cylinders, referred to as tubes or pipes, subjected to large cyclic bending, through a rigorous finite element simulation. The bent cylinders ... -
Buckling of Thin-Walled Long Steel Cylinders Subjected to Bending
(2011)The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on stability design. The cylinder response ... -
Denting of internally pressurized tubes under lateral loads
(2006)The present work examines the structural response of tubular members subjected to lateral quasi-static loading, imposed by wedge-shaped denting devices, in the presence of internal pressure. First, tubes are modeled with ... -
Free vascularized fibular grafting following failed core decompression for femoral head osteonecrosis
(2007)The results of treatment of femoral head osteonecrosis with free vascularized fibular g-rafting (FVFG) following failed core decompression (core decompression-FVFG [CD-FVFG] group: 32 hips) were reviewed and compared with ... -
Lateral loading of internally pressurized steel pipes
(2007)This paper examines the denting response of pipes subjected to lateral (transverse) quasistatic wedge loading, in the presence of internal pressure. Pipes are modeled with nonlinear shell finite elements and a simplified ... -
Outcome after tantalum rod implantation for treatment of femoral head osteonecrosis
(2009)Background and purpose Tantalum rod implantation has recently been proposed for treatment of early stages of femoral head osteonecrosis. The purpose of our study was to report the early results of its use in pre- and ... -
The role of MR imaging in staging femoral head osteonecrosis
(2007)Reliability, accuracy and prognostic value of any classification system are important in evaluation and treatment of femoral head osteonecrosis. The purpose of the present study was to correlate the plain radiographs with ... -
Simulations of insonated contrast agents: Saturation and transient break-up
(2013)Under insonation contrast agents are known to perform nonlinear pulsations and deform statically, in the form of buckling, or dynamically via parametric mode excitation, and often exhibit jetting and break-up like bubbles ... -
Stability of long transversely-isotropic elastic cylindrical shells under bending
(2010)The present paper investigates buckling of cylindrical shells of transversely-isotropic elastic material subjected to bending, considering the nonlinear prebuckling ovalized configuration. A large-strain hypoelastic model ...
