The generalized plane quasistatic deformations of linear piezoelectric laminated plates are analyzed by the Eshelby–Stroh formalism. The laminate consists of homogeneous elastic or piezoelectric laminae of arbitrary thickness and width. The three-dimensional differential equations of equilibrium for a piezoelectric body are exactly satisŽ ed at every point in the body. The analytical solution i...

magnetic field effects on the elastic response of polymeric piezoelectric cylinder reinforced with carbon nanotubes (cnts) is studied. the cylinder is subjected to internal pressure, a constant electric potential difference at the inner and outer surfaces, thermal and magnetic fields. the mori-tanaka model is used for obtaining the equivalent material properties of the cylinder. based on the ch...

Free vibration of laminated composite shells with cutouts are presented by a nine noded curved C0 finite element (FE) formulation developed by authors based on higher order shear deformation theory (HSDT) using Sander's approximations. The proposed model satisfies parabolic distribution of transverse shear strains through the shell thickness and zero transverse shear stress conditions at shell ...

This paper describes the development of an efficient finite element model for dynamic analysis of laminated beams treated by a constrained viscoelastic layer. The finite element model is designed so as to represent the viscoelastic core shear accurately. An offset-beam element which takes shear deformation into account and is specially suited for modeling such laminated beams is developed. The ...

We deal with a solid manifold block and a laminated manifold block that are used for connecting hydraulic components. They are useful for reducing the space and weight of hydraulic systems. We investigate pressure drops of their pipe flow with computational fluid dynamics (CFD) and compare those of two types. The majority of all pressure drops in both types is pressure drop at corners. In solid...

The purpose of this study is to calculate the bending deflection which used investigate largest Lyapunov exponent due buckling load. design methodology parameter at different thickness ratios and fiber volume fractions using one two stiffeners in order reduce chaotic phenomenon. practical implication find a strain gauge through meter, algorithm average logarithmic divergence experimentally. exp...

For some years in this laboratory the principles and methods of quantitative histochemistry introduced by Linderstr#{216}m-Lang and loiter (7, 10) have been used for studies on the chemical pathology of the nervous system. A particular effort has been made to describe the biochemical architecture of rat and human cerebral cortex, primarily because of its intrinsic neurological importance and th...

a new method for determination of residual stresses in the bottom layers of laminated composites is developed. in this method the residual stresses are determined by performing a consecutive drilling of laminated composites in the center of the rosette and recording the strains after drilling each layer. the depth of the hole in each step is equal to the thickness of each layer and the maximum ...

In the comparison test, we evaluated pinhole resistance in three ways, since it was not clear what evaluation methods corresponded to the pinhole resistance on the manufacturing line. The test methods employed were Gelbo flex after 30 cycles, puncture strength (by sticking a pin head into the laminated structure), and press through contamination (by putting a laminated sample between #180 sandp...

This research proposes new methods to generate rapidly complex folded plate structures that can be built with cross laminated timber panels. Composition and dimensions of these panels as well as the possibility to mill them by Computer Numerically Controlled machines, show a great potential for surface structures. The aim of this research is to reveal this potential in the domain of folded plat...
