Nonlinear static and dynamic performance of CNT reinforced and nanoclay modified laminated nanocomposite plate

Abstract

Under static and dynamic loading circumstances, the mechanically and thermo-initiated nonlinear static and dynamic assessment of the bending response of single-walled carbon nanotubes’ (CNTs’) fibers with a nanoclay particle reinforced polymer hybrid laminated composite plate is investigated. To evaluate the effective elastic characteristics of the CNTs’ fibers on the nanoclay particle modified polymer hybrid laminated plate, a modified Halpin–Tsai method is applied in an orthotropic way. The theory of higher-order shear deformation and complete kinematics (nonlinear) are used to develop the fundamental nonlinear dynamic formulation. A user-interactive finite element method-based MATLAB program solves the governing equations for nonlinear dynamic systems utilizing Newmark’s period integration and the Newton–Raphson method. The effects of variation in the quantity of CNTs’ fibers and particles of nanoclay, presence of interphases around CNTs’ fibers and nanoclay particles, variation in phases of the CNTs’ fibers on the nanoclay particle modified polymer hybrid laminated plate, and variation in plies of the laminated hybrid plate under clamped and simply supported conditions on the transverse central deflection response are explored in depth.

Regression model-based parametric analysis of drilling of multi-walled carbon nanotubes-added glass fiber composite laminates

“…F-statistic is a representation of joint variable comparison and its higher value (56. 30) is an evidence of statistical significance of the developed model. Similarly, higher t-values for feed and feed×feed indicate that the corresponding null hypothesis can be rejected, and the explanatory variables are significant, proving influence of feed rate on thrust force.…”

“…The extensive research in this field, as evidenced by studies such as those conducted by Bayraktar and Turgut [21], Kastabha et al [22], Raja et al [23], Mohan Kumar et al [24], and others [25][26][27][28][29][30][31], highlights the critical importance of understanding the effects of various drilling parameters. These studies have collectively advanced the knowledge of how factors like feed rate, cutting speed, drill geometry, and material composition influence drilling outcomes such as delamination, thrust force, surface roughness, and hole quality.…”

Prediction of Mechanical Properties of FDM Printed PLA Parts using Response Surface Methodology.

“…Omar Hamad at el. [41] analysed the influence of critical FDM process parameters such as layer thickness, air gap, build orientation, raster angle road width, and number of contours, on build time, feedstock material consumption and dynamic flexural strength [18], [33], [35], [42]- [45] using Qoptimal response surface methodology [10], [43], [46], [47]. They concluded that flexural strength or flexural modulus improves significantly using increased layer thickness [41].…”

Design Modification and Analysis of Disc Brake

“…Drum brakes: The interior side of a revolving drum expands and rubs against the shoes or lining [34][35][36]. When braking, the shoe or brake lining expands or moves outward to attach itself to the brake drum, creating friction that slows or stops the drum from rotating.…”
