Summary: This study focuses on the buckling temperature and post-buckling analysis of a functionally graded graphene nanoplatelet-reinforced composite (FG-GPLRC) disk surrounded by a nonlinear elastic foundation and covered with a piezoelectric actuator. The results demonstrate the significant impact of various factors such as radius ratio, GPLs parameters, elastic foundation, applied voltage, and piezoelectric thickness on the thermal post-buckling response of the FG-GPLRC disk. Additionally, the presence of the elastic foundation appears to induce a sinusoidal effect on the post-buckling behavior of the disk.

Results demonstrated the need for over 16 iterations to achieve convergence of the PSO and GA, and showed a 27% increase in phase velocity of the nanosystem when incorporating the proposed algorithm.

Summary: In this study, the thermal treatment of Linear Fresnel Reflector (LFR) unit was enhanced by the application of multi-way twisted tape (MWTT). Finite volume simulations were used to predict the flow and thermal performance, and SolTrace and ANSYS FLUET were used to extract the distribution of absorb flux. The results showed that the rotation, width, and number of wings of the twisted tape significantly affected the fluid flow and thermal efficiency.

Summary: A mathematical model was developed for the nonlinear frequency and chaotic responses of graphene nanoplatelets-reinforced composite annular plate subject to external harmonic load, using Hamilton's principle and von Karman nonlinear theory. The study utilized generalized differential quadrature method and perturbation approach to accurately solve the nonlinear governing equation. Results showed that the chaotic motion and nonlinear frequency of the annular plate are hardly influenced by the length to thickness ratio of graphene nanoplatelets, and using GPLs with shapes close to square could lead to higher frequency response.

Summary: Fiber-reinforced composites have been widely used in aviation and aerospace industries due to their high-strength performance. However, their complex structure makes them difficult to machine. This review summarizes the progress in understanding the damage formation mechanisms and the strategies to suppress them during milling and grinding of fiber-reinforced composites. The review covers mechanisms of milling damage, grinding mechanisms, and various suppression strategies such as ultrasonic vibration-assisted machining, cryogenic cooling, minimum quantity lubrication (MQL), and tool optimization design.

Summary: The tribological behavior of cutting is crucial in determining the production cycle, cost, and quality of parts. Minimum quantity lubrication (MQL) based on environmentally friendly biolubricants can modify the contact conditions in cutting zones, but it cannot meet the requirements for machining difficult-to-machine materials. This study comprehensively analyzed the lubrication mechanism and technical performance of enhanced MQL in turning, and conducted a comparative assessment of cutting force, cutting temperature, tool wear, and surface quality under enhanced environmentally friendly lubrication turning. The study provides insights into the mechanism, tribological behavior, and development trend of lubrication in relation to continuous cutting.

Summary: The study investigated the vibrational behavior of a three-layered sandwich microplate with functionally graded porous materials as core and piezoelectric nanocomposite materials as face sheets. By reinforcing the face sheets with carbon nanotubes, their properties can be changed, and equations of motion can be derived using innovative theoretical methods. Results show that an increase in CNTs' volume fraction improves mechanical properties and natural frequency, while the hygrothermal environment also has significant effects on the results.

Summary: This paper presents a study of the free vibration and buckling analyses of functionally graded carbon nanotube-reinforced (FG-CNTR) laminated non-rectangular plates using a four-nodded straight-sided transformation method. The geometric transformation formulation via discrete singular convolution (DSC) is used to transform the equations of motion and buckling from the irregular physical domain into a square computational domain. The numerical solutions show the effects of various parameters on the vibration and buckling analyses of the FG-CNTR-laminated composite non-rectangular plates.

Summary: This study introduces an analytical strategy for investigating the stability and frequency characteristics of nano-sized rectangular plates by modifying the nonlocal couple stress theory, discussing the impact of size-dependent factors on the performance of piezoelectric NEMS. The results show that the length of the nanoplate and l/h factor directly affect the performance of piezoelectric nanoplates, but in some cases, like when the l/h factor is large, frequency performance may not change.
