Thermal post-buckling of circular plates

The thermal post-buckling behaviour of isotropic circular plates has been studied in this paper through a simple finite element formulation. The accuracy of the solution by finite element method is established through a solution by Rayleigh-Ritz method for simply-supported circular plates. Effect of non-linearity on the load parameter is found to be much higher in the case of thermal loading than in the case of mechanical loading.     

Non-linear bending of antisymmetric cross-ply plates

The bending of antisymmetric cross-ply plates, based on Von-Karman plate theory, is investigated in this paper with one term approximations for the in-plane and transverse displacements. Rayleigh-Ritz solutions are presented for the non-linear response of cross-ply laminates with various modular and aspect ratios and subjected to sinusoidal transverse loading.     

Post-traumatic middle cerebral artery occlusion: case report and review

Occlusion of extracranial carotid and vertebral arteries following closed craniocervical trauma is well known. However occlusion of intracranial arteries following closed head injuries is infrequently reported. In fact only 25 cases of post-traumatic middle cerebral artery occlusion have been adequately documented. This entity bears re-emphasis not only because of its rarity but also because of its clinical similarity to other intracranial mass lesions.

Nonlinear vibrations of thick plates using mindlin plate elements

Large amplitude vibrations of Mindlin plates are studies using Lagrangian, isoparametric, quadrilateral elements with selective integration. Square, rectangular, circular and elliptical plates with clamped and simply supported boundary conditions are considered.     

Thermal buckling of circular plates with localized axisymmetric damages

Thermal buckling analysis of circular plates with localized axisymmetric damages has been carried out using the finite element method. The damages are characterized as degradation in material properties locally. Thermal buckling load parameters are evaluated for both simply supported and clamped circular plates with varying locations, magnitudes and lengths of damage. Numerical results are presented for different cases, and trends in variations of load parameters are discussed.
