Summary: Research on thermoelectric materials has mainly focused on enhancing their conversion efficiency, but understanding and tailoring their mechanical performance is crucial for their long-term use. Extended operation of thermoelectric materials can lead to stress-induced deformation, which affects their strain and causes damage. This review addresses the current understanding of stress-induced deformation and its impact on thermoelectric materials, and identifies new areas of research.

Summary: This paper presents a theoretical study on predicting the behavior of carbon fiber reinforced polymer-to-concrete bonded joints under fatigue-cyclic loading. A model taking into account the plastic deformations, damage, and damage accumulation is proposed. The model is calibrated using the experimental bond-slip relation and a numerical algorithm is formulated to simulate the fatigue bond behavior. The numerical simulation provides conservative predictions for fatigue life due to the neglect of beneficial effects from the compression stress state near the loaded end in the single-shear pull-off test.

Summary: This study presents the results of compressive fatigue investigations on four high-strength concretes and their corresponding mortars. The influences of coarse aggregates, substitution of basalt coarse aggregate by granite, addition of silica fume, and variation of the water to cement ratio were systematically investigated. The results show that coarse aggregates can affect the fatigue behavior of concretes differently at different stress levels compared to mortars. Granite coarse aggregate decreases the adverse effect at higher stress levels, while silica fume improves the fatigue behavior strongly. The increase of the w/c ratio reduces the fatigue resistance significantly due to the weakening of the mortar matrix and interfacial transition zone.

Summary: This study investigated the fatigue damage of CFRP composite specimens using thermal methods, aiming to evaluate the relationship between damage and the number of cycles. The damage process was studied based on a global indicator, stiffness decay, as well as local parameters, such as temperature maps during fatigue tests. A direct correlation between the damage index and temperature variation in the most stressed area was found. The heating rate during the initial cycles was also considered as a useful parameter.

Summary: Shape memory alloys (SMAs) are a new generation of smart metallic materials with unique characteristics. Preloading SMA wires for mechanical training is proposed to overcome the functional fatigue drawback and achieve stable mechanical properties. The influence of different training parameters, such as strain amplitude, frequency, number of cycles, and prestrain, on the mechanical behavior of SMA wires is examined, with training frequency being the most important parameter for eliminating residual strain.

Summary: Fatigue tests were conducted on Al alloy-CFRP riveted single-shear lap joints. Dynamic response signals were processed to study the relationship between displacement, stiffness, dissipated energy, and different failure behaviors, revealing the evolution of service state and fatigue failure process. Results showed that higher load amplitudes altered the interface slip state, increasing the dissipated power. The weak point of the joint shifted from the aluminium alloy lap plate to the CFRP lap plate, reflected in the change of failure mode.

Summary: Polymer composites are considered as a potential alternative for Joule heating materials, with the construction of a continuous conductive network of fillers remaining a challenge. A three-dimensional graphene-based aerogel infiltrated with epoxy demonstrated excellent Joule heating performance, showcasing high electrical and thermal conductivity along the parallel direction to the lamellar structure growth. The induced steady-state temperature was found to have a linear relationship with the electrical and thermal conductivities of the materials, indicating potential for thermal management applications.

Summary: A riveting method with a gasket was developed for CFRP/CFRP joints. The study evaluated the riveting damage behaviors and conducted a parametric study of the rivet rod length. Results showed that the damage mainly occurred near the rivet deformed head, due to excessive deformation of the rivet tail. Using an appropriate gasket significantly reduced riveting damage and enhanced the joining strength of the composite specimen. This paper provided a useful joining method for aircraft composite structures.

Summary: This paper investigates the damages caused by bolt insertion in Carbon Fiber Reinforced Polymer (CFRP) interference fit bolted joints. The mechanical behaviors of the joints under static and cyclic loads were experimentally evaluated. The results show that the hole entrance in the upper laminate and the laminate boundary near the hole wall are the most critical regions for damages during bolt insertions. However, these damages have minimal influence on the static failure loads and fatigue failure modes of the joints. The interference fit can improve the fatigue resistance of the laminate hole, but the bolt seems to experience a more critical local fatigue loading condition.

Summary: The application of prestressed CFRP for strengthening steel structures can reduce interfacial stress and delay debonding. Loss of prestress mainly occurs during the hardening stage of the adhesive layer, with the end anchorage system showing effectiveness. Adhesive microcracks induced by fatigue damage and degradation from wetting/drying cycles significantly impact interfacial bonding.

Summary: In this paper, a new form-finding method based on spatial elastica model (FMSE) is proposed for elastic gridshells. The method integrates the deformations of elastic rods into the overall deformation of the gridshell, and solves a set of transcendental equations using the quasi-Newton method to ensure the deformation satisfies the given boundary conditions. The method is validated through experiments and expected to have potential applications in the investigations of elastic gridshells.

Summary: The conventional evaluation of 3D braided composites' mechanical properties through numerical and experimental methodologies hinders material application due to the expenses, time constraints, and laborious efforts involved. This study establishes a multi-scale finite element model and a surrogate model for predicting the elastic properties of 3D4D rotary braided composites with voids. By optimizing a neural network model, the results are validated and provide valuable insights into the microstructure and properties of these composites.

Summary: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).

This method combines the fast convergence and ability to handle arbitrary boundary conditions of the Ritz method with the power flow equation of the statistical energy analysis method. The results show that this approach effectively filters out random fluctuations in mid-frequency domains while demonstrating exceptional stability and precision.

Summary: This paper presents a study on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. The specimens were tested under compression loading conditions to investigate post-buckling and failure in aerospace structures. Experimental results and numerical simulations were compared to analyze the behavior and failure modes of the specimens. The study found promising evidence of a viable solution to optimize aeronautical structures and enhance resistance to skin-stringer separation, particularly with the use of tapered flanges.
