Summary: A meshfree method that combines the first-order shear deformation theory with moving least-squares approximation is proposed for static and dynamic investigations of composite laminated stiffened plates. The method considers the coupling effects in laminated plates and torsional effects and out-of-plane deformations for laminated ribs. By establishing displacement fields using MLS and FSDT, and proposing a transformation equation for the nodal parameters between laminated rib and laminated plate, the equations governing the bending and free vibration of the stiffened plates are obtained. The results show the effectiveness and accuracy of the method in analyzing the bending and free vibration properties of composite laminated stiffened plates.

Summary: Based on the material nonlinearity of carbon fiber reinforced composites (CFRC) obtained in previous work, this paper further studies the nonlinear dynamical behaviors of bolt-connected CFRC plates. A joint parameter identification method is proposed to accurately identify the nonlinear mechanical parameters of the joint interface. A combined nonlinear parameter tracking model is developed to capture CFRC-material and joint nonlinearity. The analysis of a bolt-connected CFRC plate demonstrates the effectiveness of the proposed models in tracking parameters and simulating the mechanical behavior of the joint.

Summary: Kernel Partial Least Squares (KPLS) is an effective nonlinear modeling technique used in control engineering applications, capable of handling small sample sizes and noisy, highly correlated variable sets. By mapping input variables to a feature space, it produces an optimal prediction model for process output variables. However, the computational intensity of the procedure can be a challenge, especially when dealing with large data sets. The proposed Efficient Kernel Partial Least Squares (EKPLS) aims to reduce computational complexity significantly compared to the traditional approach.

Summary: Compared with the finite element method, H2-regularity in the Galerkin based approximation to the Kirchhoff thin plate model can be easily realized using either the moving least squares (MLS) or the generalized moving least squares (GMLS), which take the Lagrange form and the Hermite form, respectively. Coupling (G)MLS with the numerical manifold method (NMM) can greatly improve numerical properties of NMM in the treatment of plates of complicated shape, thereby denoted by MLS-NMM and GMLS-NMM. However, through numerical tests and theoretical analysis in solving problems of thin plates on elastic foundations, this study shows that MLS-NMM is much more advantageous over GMLS-NMM from the aspects of both accuracy and memory usage.

Summary: This study presents a modified differential quadrature (MDQ) method to investigate the dynamic response of perforated plates under uniaxial impact compressive load. By introducing the penalty function method, the continuity of the plate elements is ensured along the shared edges to consider the effect of elastically restrained edges. Through verification analysis and investigation of various factors, it is found that the dynamic buckling load of perforated plates is mainly influenced by rotational restraint stiffness, hole size, and shear load.

An analytical approach based on the Galerkin method is used to solve the governing nonlinear differential equations, resulting in a closed form equation of motion solved by the fourth-order Runge-Kutta method. The proposed method is verified and shown to yield results with less than 2% error compared to previously published papers.

Summary: This article investigates the frequencies of tangential waves in Functionally Graded (FG) sandwich Merged Hemispherical-Cylindrical Shells (MHCS) with free-damped vibration characteristics. The three-layered MHCS contains Functionally Graded Material (FGM) with functional variation along the thickness. The mechanical features of the materials are determined using Equivalent Single Layer (ESL) and Rule of Mixture (RM). Eight sandwich types are examined, assuming flexible merging and support conditions. The article utilizes Donnell's hypothesis and Hamilton's scheme to acquire the kinetic differential equations and applies the Generalized Differential Quadrature Method (GDQM) to discretize the equations and determine the tangential wave frequencies.

Summary: The aim of this paper is to study the size-dependent geometrical nonlinear static characteristics of curved panels enriched by nano-additives incorporating thermal effects. The size-dependency is considered by developing the basic equations based on the modified couple stresses theory (MCST). An analytical approach based on the Galerkin method is used to find the response of the achieved set of nonlinear differential equations and obtain a closed-form pressure-deflection relationship representing the nonlinear equilibrium path of the curved micropanels. The closed-form relationship is examined and a parametric numerical study is conducted to investigate the effects of material length-scale parameter (MLSP) and the characteristics of geometry and material on the geometrical nonlinear path of equilibrium.

Summary: This research focuses on analyzing rotating truncated conical baskets reinforced by carbon nanotubes around two independent axes. A time-dependent analysis is used to extract the nonlinear dynamic governing equations for the structure. Carbon nanotubes are used to reinforce the conical basket, with different distributions impacting the mechanical properties. The resistance of a novel two-axis rotating conical basket as a centrifuge device is investigated at various rotational velocities. The results show that reinforcing the basket with carbon nanotubes increases its resistance against deformation caused by rotation.

Summary: The influence of crystal size on the macroscopic parameters of sandstone samples is studied using a rock model based on the Voronoi tessellated model. It is found that decreasing crystal size results in increased strength and elastic modulus. Strain energy density (SED) is shown to help explain the failure mechanisms of the sandstone samples. A constitutive model that considers the heterogeneity in elastic modulus and rock strength is developed and is in good agreement with experimental results. The study also identifies the triggering of surface damage on slopes by vibration excitation in engineering applications as well as proposes a constitutive model for quantitatively evaluating damage accumulation in mining tunnels.

Summary: This paper presents a novel numerical approach for nonlinear analysis and smart damping control in laminated functionally graded carbon nanotube reinforced magneto-electro-elastic (FG-CNTMEE) plate structures, taking into account multiple physical fields. The approach employs a multi-physical coupling isogeometric formulation to accurately capture the nonlinear strain-displacement relationship and the magneto-electro-elastic coupling properties. The smart constrained layer damping treatment is applied to achieve nonlinear damped responses. The formulation is transformed into the Laplace domain and converted back to the time domain through inverse techniques for smart control using viscoelastic materials.
