The present paper investigates the advantages of a new class of composite grid structures over conventional grids. Thus far, a known grid structure such as orthogrid or isogrid has been used as an orthotropic layer with at most in-plane anisotropy. The present laminated grid is composed of various numbers of thin composite grid layers. The stiffness of the structure can be adjusted by choosing ...

The partially prefabricated laminated (RC) walls mentioned is this kind of seismic prevention element with part prefabricated concrete plate and cast in place concrete plate. 4 typical laminated walls without openings, 4 laminated walls with openings, and 1 common cast-in-place RC walls were tested under cyclic test. The seismic behaviour were analysed by the finite element software based on th...

We investigate the global bifurcations and multipulse chaotic dynamics of a simply supported laminated composite piezoelectric rectangular thin plate under combined parametric and transverse excitations. We analyze directly the nonautonomous governing equations of motion for the laminated composite piezoelectric rectangular thin plate. The results obtained here indicate that the multipulse chao...

Cross-laminated timber is increasingly being used in the construction of high-rise buildings due to its simple manufacturing system. In term of fire resistance, cross-laminated timber panels are promoted as having excellent fire resistance, comparable to that of non-combustible materials and to heavy timber construction, due to the ability of thick wood assemblies to char slowly at a predictabl...

In this paper, three fundamental techniques to improve laminated passive elements are proposed for wearable haptic displays. First, a new shape of sheet surfaces in laminated passive elements is introduced. Sliding motion between laminated sheets causes unexpected bad effect to static stiffness. An effective triangle shape for sheet surfaces, which prevents from sliding, has been analyzed. This...

The cage and reluctance rotors are two major types of rotor structures used in the doubly fed brushless machine (DFBM). In order to study comparatively the effects of different rotor structure on the DFBM, a prototype machine has been specially designed and built. The experimental parameter and performance comparisons between the axially laminated anisotropic (ALA) and cage-rotor machines are p...

The metacestode (larval) stages of the cestode parasites Echinococcus vogeli and E. multilocularis were isolated from the peritoneal cavity of experimentally infected C57BL/6 mice and were cultured in vitro for a period of up to 4 mo under conditions normally applied for the in vitro cultivation of E. multilocularis metacestodes. In contrast to E. multilocularis, E. vogeli did not exhibit exten...

Fiber-reinforced laminated composites are frequently preferred in many engineering projects. With the development in production technology, the using of the fiber reinforced laminated composites has been increasing in engineering applications. In the production stage of the fiber-reinforced laminated composites, porosities could be occurred due to production or technical errors. After a level o...
