Lateral thermal buckling of pipelines on the sea bed
… for protection and to mitigate against upheaval buckling becomes increasingly impractical. In addition, the exploration of new reservoirs at higher temperatures and pressures than before leaves a submarine pipeline on the seabed more susceptible to lateral thermal buckling. A novel small-scale …

Thermal buckling and postbuckling of symmetrically laminated composite plates
This paper discusses an investigation into thermal buckling and post-buckling of symmetrically laminated composite plates. In this study, thermal buckling is investigated for laminates under two different simple support conditions, fixed and sliding. These laminates are subjected to the conditions …

Finite Element Analysis of Thermal Buckling in Automotive Clutch and Brake Discs
<p>Thermal buckling behavior of automotive clutch and brake discs is studied by making the use of finite element method. It is found that the temperature distribution along the radius and the thickness affects the critical buckling load considerably. The results indicate that a monotonic …

Coupling Numerical Analysis of Vibration and Thermal Buckling of an Automotive Brake Disc
… This high temperature gradient in turn induces thermal buckling. During high speed rotation, vibration is likely to occur in the system. In terms of a brake disc vibration will occur when there is a misalignment of the brake disc or thermoelastic instability (hot spot) forms on the brake rotor. …

Finite Element Analysis of Thermal-Mechanical Instabilities in Nonmetallic Friction Composite Material
<p>Thermal-mechanical instability (TMI) has been a research topic of interest as it focuses a lot on transportation systems. Thermal-mechanical instability was first noticed in railway and experimentally studied with a pin-to-pin or pin-to-surface setup of sliding contact. The topic has been …

Thermomechanical Stability of Automotive Clutches and Brakes
… were performed to evaluate the stability thermal buckling existing in clutch disks. The commercial software ABAQUS had been used. It was discovered that monotonically increasing thermal loads constantly result in axisymmetric buckling modes. When the maximum values of thermal loads were …

Steady and Unsteady Thermo-Strucural Simulation of Thermally Actuated Micro- and Nano-Structures
… and fixed boundary conditions which are either thermally positioned, buckled, or actuated. The study begins with simulating a pinned-pinned beam in micro-scale and nano-scale. The steady state thermo-structural equation is solved numerically using an implicit Finite Difference method implemented …

Thermal Analysis and Response of Grid-Stiffened Composite Panels
A study aimed at determining the thermal deformation response and thermal buckling loads of rectangular grid-stiffened composite panels is presented. Two edge conditions are considered for the panel, one in which all panel edges are free to deform, and another when all the edges are restrained. In …
