This is the first part of a two-part paper dedicated to a new plate theory for out-of-plane loaded thick plates where the static unknowns are those of the Kirchhoff-Love theory (3 in-plane stresses and 3 bending moments), to which six components are added representing the gradient of the bending moment. The new theory, called the Bending-Gradient plate theory is described in the present paper. ...

We have successfully prepared nanohybrids of biofunctional ferulic acid and layered double hydroxide nanomaterials through reconstruction and exfoliation-reassembly routes. From X-ray diffraction and infrared spectroscopy, both nanohybrids were determined to incorporate ferulic acid molecules in anionic form. Microscopic results showed that the nanohybrids had average particle size of 150 nm wi...

In this paper a numerical model to study the vibro-acoustic behavior of a laminated plate backed by a poroelastic foam layer is developed. Such approach consists on a coupled mitigation strategy aiming either mechanical vibration suppression or acoustic attenuation as well. The laminated plate model consists of fiber laminae with interleaved viscoelastic layers in standard constrained or integr...

In this study, the torsional stability analysis is presented for thin cylindrical with the functionally graded (FG) middle layer resting on the Winker elastic foundation. The mechanical properties of functionally graded material (FGM) are assumed to be graded in the thickness direction according to a simple power law and exponential distributions in terms of volume fractions of the constituents...

Large lakes can both produce and record significant crustal deformation. We present an analysis of the isostatic rebound pattern recorded in the shorelines of paleo-lake Lahontan, in western Nevada, using a layered Maxwell viscoelastic model. The inferred viscosity structure depends on loading history. We use three variants of a well documented lake surface elevation model as input and recover ...

Madal performance is the basic characteristics of structures, which will help to further understand vibration structures. Besides, fluid (e.g. water) coupled with structure strongly affact modal structure. To get clear performance, Modal tests are conducted for two-layered plate both in air and water, frequency mode shape given. With comparative analysis frequencies these two cases, it’s shown ...

Abstract Multi-layered composite shells are extensively used in many industrial fields since they have superior performance applications. As load-carrying components, buckling failure is one of the most common modes multi-layered shells. Hence, layup design based on optimal factors widely concerned, where lamination parameters commonly representation stiffness. However, formulations laminate st...
