In this study in-plane mechanical properties of continuous carbon fibre reinforced thermoplastic polyamide composite manufactured using a Markforged Two 3D printing system was evaluated and compared against predicted values from classical laminated-plate theory. Strength, stiffness Poisson’s ratio the specimens were measured tensile testing both in longitudinal transverse direction shear also m...

Composite materials are used in aeronautical, automobile, healthcare and marine industries due to their high stiffness, higher strength-to-weight ratio long fatigue life. Thin plate plays vital role manufacturing of engineering structures. Components made from composite often subjected damage while working. Buckling can cause loss stability component which subsequently leads failure the entire ...

In the present study, small scale effect on critical buckling loads of triangular nano- composite plates under uniform in-plane compression is studied. Since at nano-scale the structure of the plate is discrete, the size dependent nonlocal elasticity theory is employed to develop an equivalent continuum plate model for this nanostructure incorporating the changes in its mechanical behavior. The...

In this paper, a continuum model based on the nonlocal elasticity theory is developed for vibration analysis of embedded orthotropic circular and elliptical micro/nano-plates. The nano-plate is bounded by a Pasternak foundation. Governing vibration equation of the nonlocal nano-plate is derived using Nonlocal Classical Plate Theory (NCPT). The weighted residual statement and the Galerkin method...

In this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plate is presented using the higher order shear deformation theory. The face sheets are orthotropic laminated composites that follow the first order shear deformation theory (FSDT) based on the Rissners-Mindlin (RM) kinematics field. The motion equations are derived considering the c...

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...

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 ...
