“…Many researchers have also utilized nanomaterials as fillers in the composite materials that have widened the application spectrum of composites. [21][22][23][24][25][26][27] Arshid et al 28 investigated the effect of reinforcing graphene nanoplatelets on the porous nanocomposite annular plate. In another work, thermo-mechanical buckling analysis of honeycomb microplates integrated with graphene nanoplatelets reinforced epoxy skins was performed by Khorasani et al 29 Amir et al 30 investigated the vibration of a porous rectangular plate located between two piezo-electromagnetic layers.…”

Agro-wastes have a huge potential to be utilized as lignocellulosic reinforcements in polymer composites. This will not only play an important role in waste management but will also strengthen sustainable production. In the present work, pine cones and wood apple shells were utilized as fillers along with areca sheath fibers in bio-based epoxy resin for fabricating a novel hybrid composite wherein the effect of these fillers in laminated composites has not been explored to a greater extent. The impact of reinforcing both types of fillers in different loadings (5, 10, and 15 wt.%) on various properties of composites was investigated. Physical properties like density, void fraction, mechanical properties comprising of tensile, flexural, interlaminar shear strength (ILSS), and hardness along with morphology and moisture absorption behavior of composites were investigated. The mechanical properties of the fabricated composites were influenced by the structure (coarser/finer) of fillers and their chemical composition. The mechanical results for the composites revealed that incorporating wood apple shell fillers resulted in the maximum rise in tensile (23.97%), impact strength (16.81%), and interlaminar shear strength (31.64%), while the incorporation of pine cone fillers resulted in the maximum rise of flexural strength along with Young's (35.4%) and flexural modulus (32.81%). A reduction in moisture absorption was observed on the addition of both types of fillers up to a certain filler loading. The investigations demonstrated a noticeable enhancement in mechanical and physical properties of the fabricated composites on reinforcing micron size fillers.

The purposes of this paper are to study bending, buckling, and vibration by considering micro-scale effects using the Kirchhoff thin-plate theory and to consider small deflections, neglecting higher-order nonlinear terms. The governing equations for the bending, buckling, and vibration of the system are obtained using the equilibrium method coupled with the Kirchhoff thin-plate theory and a modified couple stress theory (MCST). The concept of the equivalent bending stiffness (EBS) of micro-thin plates is proposed to describe the scale effect. The Navier method is used to obtain analytical solutions for the bending, buckling, and free vibration of thin plates under simply supported boundary conditions with scale effects. The numerical results are presented to investigate the influence of scale effects on deflection, critical buckling load, buckling topography, and thin-plate natural frequency. The results show that the scale effect increases the equivalent stiffness of the thin plate, which leads to a decrease in deflection, a larger critical buckling load, and an increase in natural frequency, but does not affect the buckling topography. The MSCT is invalid when the thickness is greater than 10 times the scale effect parameter, thus defining the scope of application of the scale effect. This research study may contribute to the design of micro-scale devices such as MEMSs/NEMSs.

The vibrational behavior of a three‐layered annular plate is considered in the present study. The plate is composed of a functionally graded (FG) porous core which is saturated by fluid and two piezoelectric patches that are bonded to the core and are subjected to the electric field. The whole of the structure is also rested on visco‐Pasternak elastic foundation. The material properties of the FG porous core vary through the thickness direction based on different patterns which are called porosity distributions. Love‐Kirchhoff's hypothesis and Hamilton's principle is employed to extract the governing motion equations and boundary conditions and following it, they are solved by generalized differential quadrature method (GDQM) for various boundary conditions. After ensuring the validity of the results by comparing them with known data in the literature, the effect of the most important parameters on the results is considered. It is seen that the effect of the porosity coefficient on the natural frequencies is completely dependent on the pores’ distribution patterns. Also, increasing in externally applied voltage to the piezoelectric facesheets, leads the results to enhance. The outcomes of this work can help to design and create smart structures and systems such as sensors and actuators.
