Results are presented from a numerical investigation of the effect of stacking sequence on energy release rate distribution in laminated carbon fibre reinforced epoxy double cantilever beam, single leg bending and end-notched flexure test specimens. The deformation behaviour of the specimens has been computed by three-dimensional nonlinear finite element analyses using a recently developed laye...

Curved reconstruction of a three-dimensional data set along the anterior optic pathway improves visibility of the optic nerves and chiasm and facilitates comparison between the two nerves. Curved reconstruction reveals three patterns in patients with masses of the anterior optic pathway. Retrobulbar buckling of the optic nerve into a "periscope" configuration is observed in some patients.

Introduction Lead-based shields are the most widely used attenuators in X-ray and gamma ray fields. The heavy weight, toxicity and corrosion of lead have led researchers towards the development of non-lead shields. Materials and Methods The purpose of this study was to design multi-layered shields for protection against X-rays and gamma rays in diagnostic radiology and nuclear medicine. In this...

Three-dimensional dynamic problem for a layered orthotropic elastic shell with free upper face is considered. The interfaces between the layers are assumed to be in perfect contact and displacements of one prescribed. A long-wave asymptotic solution constructed thickness resonances determined. obtained results can applied evaluation some parameters earthquakes.

We consider an ideal gas of infinitely rigid rods near a perfectly repulsive wall, and show that the interfacial tension of a surface with rods on one side is lower when the surface bends towards the rods. Surprisingly we find that rods on both sides of surfaces also lower the energy when the surface bends. We compute the partition functions of rods confined to spherical and cylindrical open sh...
