Summary: This article aims to establish a dual-level fast direct solver to efficiently solve large-scale dense linear systems caused by semi-analytical boundary collocation methods. The dual-level fast direct solver constructs a sparse approximate inverse matrix to approximate the solution of linear equations. It overcomes the drawback of the GMRES in solving such systems. Practical engineering problems, such as acoustic scattering from an A320 aircraft and a human head, are analyzed using the dual-level fast direct solver.

Summary: This paper proposes a fast direct boundary element method (BEM) for 3D acoustic problems, which is more suitable for broadband acoustic simulation of complex structures. The method is based on the hierarchical off-diagonal low-rank (HODLR) matrix, randomized interpolative decomposition, and fast matrix inversion formula. Numerical examples show that the fast direct BEM achieves the same accuracy and higher computational efficiency compared to the conventional direct BEM.

Summary: An accelerated integral equations (IE) field solver using fast multipole method (FMM) is proposed for determining scattered fields from electrically large electromagnetic metasurfaces. The method utilizes an equivalent zero thickness sheet model and the generalized sheet transition conditions (GSTCs) to express the metasurfaces. By dividing the current elements on the metasurface into near- and far-groups and using either rigorous or approximated Green's function, the computation time is reduced without sacrificing solution accuracy. Numerical examples confirm the speed improvement of the FMM IE-GSTC method over the standard IE-GSTC method, and its usefulness in improving signal coverage in blind areas of an electrically large radio environment.

Summary: This paper proposes a Revised In-Place Inversion algorithm for inverting a large number of small matrices on the CUDA platform, which adopts a more refined parallelization scheme and outperforms other algorithms, achieving a speedup of up to 20.9572 times over the batch matrix inverse kernel in CUBLAS. Additionally, it is found that there is an upper bound on the input data size for each GPU device, and the performance will degrade if the input data size is too large. Therefore, the Saturation Size Curve is proposed to divide matrices into batches and improve the algorithm performance.

Summary: This study presents a framework for estimating the initial investment cost and added weight of integrating a structural health monitoring (SHM) system into an aircraft. The framework breaks down the sensorization activities and costs using wired or printed diagnostic film approaches, and considers the difference between manual and remote data acquisition. Based on a case study of a regional aircraft composite fuselage, there is a trade-off between cost and weight for different SHM options. These estimations capture the characteristics of each system and can be used in cost-benefit analyses for selecting the most suitable configuration.

Summary: This study presents a non-linear analysis method for considering damage initiation and evolution in variable angle tow composite plates under progressive loading. The model is based on first order shear deformation theory kinematics and non-linear strains in the von Karman sense. The constitutive relationships are formulated using continuum damage mechanics, allowing for in-plane damage initiation and evolution in each laminate layer. The Ritz polynomial expansion and minimization of the total potential energy provide the discrete solution equations, which are solved iteratively to capture damage evolution.

Summary: A computational framework for high-fidelity static aeroelastic analysis is presented in this paper. The framework combines a high-order structural model with a high-fidelity aerodynamics method, using the Carrera Unified Formulation and Finite Element Method. The aerodynamic fields are solved using the open-source software SU2, and a fluid-structure coupling algorithm based on the Moving Least Square technique is used. The paper provides thorough validation of each disciplinary solver and presents several application test cases. Overall, the method shows good agreement with predictions from potential flow theory for moderate freestream velocities, but deviations are observed at very low speed and in the high-subsonic regime, indicating the need for high-fidelity flow solutions at these conditions. The framework is also applied to the aeroelastic tailoring of a composite wing, and future implementation steps are discussed. Rating: 9/10.

Summary: This paper investigates the influence of internal defects, including active phase texture, CNT agglomerations, and interfacial damage, on the piezoelectric performance of composites. The study reveals that interfacial damage significantly affects the piezoelectric constants related to normal strain modes, while the constants related to shear strain remain unchanged. Near the percolation threshold of CNTs, there is a notable improvement in the piezoelectric response. The optimal texture and CNT volume fraction depend on the presence of interfacial damage.

Summary: This paper presents a Method of Fundamental Solutions (MFS) combined with Erdogan's solutions for Functionally Graded Materials (FGM) to analyze 2D fracture problems under static and dynamic loads. Erdogan derived analytical solutions for a pair of static concentrated forces in an infinite isotropic plate with a straight cut. The contribution of non-homogeneity in equilibrium equations is treated as body forces and requires domain integrals based on Erdogan's fundamental solutions. In dynamic cases, Laplace transformation and Durbin inversion technique are used to determine time-dependent variables such as stress intensity factors. Numerical domain integrals are obtained using the sub-region technique. The accuracy of MFS is demonstrated through four numerical examples and comparisons with different numerical approaches are performed.

Summary: Among the Structural Health Monitoring (SHM) systems, Guided Waves (GW) based ones have been increasingly investigated for their reliability in damage detection, low power consumption requirement, and capability in monitoring extended areas with fewer transducers. However, their use in real applications is still challenging. This research focused on the effects of GW propagation mechanisms in a composite plate at an elevated temperature of 65 degrees C using a validated Finite Element (FE) model. The decrease in GW propagation velocity at 65 degrees C was observed.

Summary: In this study, multiple collisions of granules on a substrate are analyzed using Collisional Smooth Particle Hydrodynamics (CSPH) to understand the influence of impact-induced deformation on subsequent collision dynamics. It is found that the collision dynamics are dependent on the impact location and the deformation caused by preceding impacts. The accuracy of three theoretical models is also evaluated by comparing their predictions with CSPH results, and it is discovered that these models are only useful for predicting collisions at the same location repeatedly.

Summary: This paper investigates anisotropic elastic, magnetoelectroelastic, and quasicrystal solids and presents their equations of time-harmonic motion and constitutive relations in a compact and unified form. A matrix approach is proposed to derive the 3D time-harmonic Green's functions for these materials. The effects of phason field dynamics on the phonon oscillations in quasicrystals are studied in detail. The paper provides a strict proof that the eigenvalues of the time-harmonic magnetoelectroelaticity problem are all positive. It also demonstrates the application of the obtained time-harmonic Green's functions in solving boundary value problems for these materials using the derived boundary integral equations.
