In this article, bending, buckling, and free vibration of viscoelastic sandwich plate with carbon nanotubes reinforced composite facesheets and an isotropic homogeneous core on viscoelastic foundation are presented using a new first order shear deformation theory. According to this theory, the number of unknown’s parameters and governing equations are reduced and also the using of shear correct...

In this study, the mechanical buckling response of refined hyperbolic shear deformable (FG) functionally graded nanobeams embedded in an elastic foundation is investigated based on the refined hyperbolic shear deformation theory. Material properties of the FG nanobeam change continuously in the thickness direction based on the power-law model. To capture small size effects, Eringen’s nonlocal e...

This Article argues that foundation, not relevance, embodies our fundamental understanding of admissible evidence. The foundation principle—only partially and somewhat obliquely stated in the Federal Rules of Evidence—is a requirement that evidence be case-specific, assertive, and probably true. As such, it is a logical precondition for relevance. A foundation-based theory of evidence explains,...

Introduction: The purpose of the current research was to explain the healthy lifestyle with an emphasis on the sports activities of the elderly in the country based on the data theory of the foundation. Method: The current study is a prospective qualitative applied study based on the foundational data theory, and in terms of data analysis method of analytical-exploratory type and data collecti...

in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...
