Thermal buckling of conical shells.

AIAA Journal, 1967
The instability of truncated conical shells, due to thermal loadings, is studied using the Galerkin method to integrate the equilibrium equation. The thermal stresses which depend on the boundary condition and the temperature distribution are found before solving the buckling problem. Two cases are considered in this investigation.

Thermal buckling of functionally graded plates

AIAA Journal, 2002
Equilibrium and stability equations of a rectangular plate made of functionally graded material under thermal loads are derived, based on the classical plate theory. When it is assumed that the material properties vary as a power form of thicknesscoordinate variable z and when the variational method is used, the system of fundamental differential ...

Stretching of buckled filaments by thermal fluctuations

Physical Review E, 2007
We study the buckling instability of filaments or elastic rods in two spatial dimensions in the presence of thermal fluctuations. We present an analytical solution based on a renormalization-like procedure where we integrate out short wavelength fluctuations in order to obtain an effective theory governing the buckling instability.

Scleral Buckling Without Thermal Adhesion

American Journal of Ophthalmology, 1980
One hundred seventy-five consecutive and unselected patients with retinal detachment were treated with a scleral buckling procedure without inducing a thermal adhesion. In 143 (82%) of these patients reattachment was successful after one operation. In 32 patients (18%) reattachment was not initially successful.

Buckling of a thermal plume

International Journal of Heat and Mass Transfer, 1992
Abstract The transition of a thermal plume from laminar to turbulent flow is characterized by a non-axisymmetric deformation. Past analyses are limited either to the planar plume or to the axisymmetrie assumption, and subsequently are not capable of predicting the real phenomenon.

Thermal Buckling of Offshore Pipelines

Journal of Offshore Mechanics and Arctic Engineering, 1988
Abstract The vertical buckling of offshore pipelines caused by thermal loads is analyzed by modeling the pipeline as a long heavy beam resting on a rigid foundation. The axial restraint provided to the line by the surrounding soil is modeled as Coulomb friction. The study is concerned with the effect of localized, small initial geometric

Thermal buckling of a constrained elastic ring†

International Journal of Non-Linear Mechanics, 1974
Abstract The buckling problem of a heated circular elastic ring confined to a uniformly contracting circular boundary is investigated. The buckled configuration is assumed to consist of a shallow detached region with the remainder of the ring in contact with the contracting boundary.

Thermal Buckling of Supersonic Wing Panels

Journal of the Aeronautical Sciences, 1956
WH E N THE SURFACE of a multicellular supersonic wing is heated by the air flowing in the boundary layer (see Fig. 1), the temperature of the cover plates rises and the cover plates expand. This expansion is resisted by the shear webs which remain comparatively cool as they are not in contact with the boundary layer and are heated only by the cover ...

Thermal Buckling of Dual-Coated Fiber

AT&T Technical Journal, 1985
An analysis of buckling is presented for dual-coated fibers within their coating at low temperatures. Buckling causes microbending of the fiber axis, the prime source of added optical loss in the fiber. Buckling is caused by compressive stress exerted on the fiber by the coating, which arises because the thermal expansion coefficient of the coating is ...

Thermal buckling of silicon sheet

Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference, 1988
Results of buckling analyses for three closely related thermal profiles are discussed. They come from the same basic furnace design but reflect changes that occur in the thermal profile when different pull speeds are used to produce wider or thicker ribbon. It is shown that the three profiles differ near the solid-melt interface.
