Carbon fiber reinforced polymer is a composite material, which widely used in various engineering fields due to its excellent properties. We systematically discuss the influence of axial load amplitude parameters on multiple periodic motions carbon laminated cylindrical shell model. Based Melnikov vector function, bifurcation regions orbits are obtained. It found that system has at most four un...

Abstract To explore in-plane shear failure mode of cross-laminated timber (CLT) panel, this paper carried out relevant research work from the perspective stress analysis and combined with crack morphology specimen after planar shear. In study, load–displacement curve hemlock [ Tsuga canadensis (L.) Carrière] CLT was obtained by a three-point bending test or an improved test, vertical layer azim...

A new closed form formulation of three-dimensional (3-D) refined higher-order shell theory (RHOST) to analyze the free vibration of composite circular cylindrical shells has been presented in this article. The shell is considered to be laminated with orthotropic layers and simply supported boundary conditions. The proposed theory is used to investigate the effects of the in-plane and rotary ine...

Bending tests were conducted with cross laminated timber (CLT) panels made using an alternating layer arrangement. Boards of Norway spruce were used to manufacture five-layer panels on an industrial CLT production line. In total, 20 samples were tested, consisting of two CLT configurations with 10 samples of each type: transverse layers at 45° and the conventional 90° arrangement. Sample dimens...

New spherical codes called laminated spherical codes are constructed in dimensions 2–49 using a technique similar to the construction of laminated lattices. Each spherical code is recursively constructed from existing spherical codes in one lower dimension. Laminated spherical codes outperform the best known spherical codes in the minimum distance sense for many code sizes. The density of a lam...
