Summary: In this study, a numerical simulation model was established to investigate the induction welding process and joint failure for CF/PPS-Al interlocking welding. The results showed that the addition of macro-scale interlocking features significantly improved the ultimate load of the welded joints. The number of addition PPS films and the inclination angle also had a greater contribution to the tensile strength of the joints.

Summary: In this study, the shear performance of a new type of interlocking brick is systematically investigated. Laboratory shear tests and numerical models are used to study the shear capacity and influences of different factors on the shear response of interlocking prisms. An empirical design formula is proposed based on the results to predict the shear capacity of the interlocking brick.

Summary: This study analyzed the mechanical performance of the assembled lunar landing pad and found that the assembly pattern, size, and thickness of the prefabricated modules are important factors affecting the structural performance. The results also showed that the thickness of the modules has a greater influence on the structural performance than the load position and size. This study is expected to provide a reference for the design and construction of lunar landing pads.

Summary: A new lattice structure, named the interlocking-circles lattice, is proposed to generate isolated flat bands in graphene by hydrogenation. This structure results in the splitting of flat bands into spin-polarized bands upon hole or electron doping, leading to ferromagnetic graphene. This work not only introduces a new lattice type, but also provides a pathway to search for systems with isolated flat bands.

Summary: Steel-concrete composite structures are widely used in on-site constructions, but prefabricated composite slabs face challenges due to insufficient research and information on connection systems. This study proposes an interlocking connection system for prefabricated composite slabs, showing a 40% higher ultimate load capacity compared to simply supported non-composite slabs.

Summary: By simulating the micro layered structure of nacre, the mechanical and damage characteristics of AA7075-T651/toughened epoxy resin composites were investigated, and it was found that increasing the number of layers and decreasing the tablet dimensions can enhance the energy absorption performance of the composite.

Summary: This study introduces a new strategy to enhance the interfacial interaction in polypropylene/aramid fiber composite by constructing a mechanically-interlocking interface through the diffusion and epitaxial growth of self-assembling compounds on the surface of the reinforcing fiber. The mechanically-interlocking effect significantly increased the interfacial shear strength and impact strength of the composite, paving the way for the production of high-performance filler-reinforced composites.

Summary: The study investigated the effect of rock shear keys on rock-filled concrete cold joints. Two failure modes were identified: one originating from self-compacting concrete and the other from rocks. Shear capacity was found to be influenced by normal pressure, exposed height, and the number of rock keys. Material strength had a different influence depending on the failure mode.

Summary: This paper presents a numerical study on the effects of particle shape and particle-fluid interaction on the formation mechanism of sandpiles in air and water. The study focuses on non-spherical particles that are commonly found in seabed sediments. The results show that the occlusal interlocking effect of non-spherical particles enhances inter-particle friction, and the influence of ambient water is also significant. These findings are important for understanding fundamental geomechanical issues, such as seabed instability induced by seawater flow.

Summary: Interlocking metasurfaces (ILMs) are a novel class of structural metamaterials that provide non-permanent joints as an alternative to traditional fasteners, welds, or adhesives. The mechanical properties of ILMs are governed by both the shape of individual latching unit cells and the interactions between unit cells, which lead to increased strength and stiffness. Experimental measurements and computational analysis confirm the cross-cell interactions and the unique deformation and failure mechanisms of ILMs, making them a promising joining technology.

Summary: This study conducted experimental research on cold-formed steel (CFS) interlocking panels under static wind uplift and cyclic pressure, and also established a nonlinear finite element model. The results show that local failure occurs around the screws near the connection of adjacent cladding sheets, leading to global failure of the entire cladding assembly. A parametric study reveals that thickness, yield stress, and span of the interlocking cladding have an impact on its wind uplift capacity.

Summary: This paper introduces a new structure of non-contacting finger seals with double interlocking pads and establishes a numerical analysis model based on the thermo-fluid-structure coupling method. The influence of working conditions on the seal leakage is studied and compared. The results show that the proposed double interlocking padded finger seal reduces the leakage factor by about 37% compared to the typical single padded non-contacting finger seal.

Summary: Developing tissues can self-organize into patterned structures through the stabilization of stochastic fluctuations in molecular and cellular properties. The fidelity of the patterns formed depends on the initial amplitude of cell anisotropy, and cell shape anisotropy is associated with proper pattern geometry.

Summary: This article presents the application of cylindrical and spherical symmetries in numerical studies of many-body problems. The use of periodic boundary conditions with cylindrical symmetry is shown to effectively reduce the influence of boundary conditions and obtain reasonably accurate results. A physically realizable cylindrical configuration is also explored. The advantages and disadvantages of symmetric realizations are discussed. Furthermore, the article investigates the use of spherical symmetry, which eliminates boundaries in a three-dimensional system. Using tectonic dynamics as an example, interesting patterns resembling real structures are found, emphasizing the potential role of perturbations in the planet's axis of rotation in their formation.
