Summary: This study proposes a method for accurately predicting the penetration failure load of composites using acoustic emission (AE) data. The method includes a cyclic loading test schedule and an extrapolation method based on uncertainty. The results show that this method can accurately predict the failure load when LR equals 1.

Summary: This study proposes and tests a novel self-centring shape memory alloy (SMA) wire-confined reinforced concrete (RC) column to enhance the seismic performance and self-centring capacity. Experimental tests were conducted on one common RC pier specimen and eight SMA-wire-confined RC pier specimens to investigate the effects of axial-compression ratio, SMA pre-strain level, and SMA configuration rate. The research results provide new ideas and experimental basis for the external strength gain and rapid recovery of existing RC piers after an earthquake.

Summary: This study investigated the effects of a nanofiber interlayer on the mechanical properties of carbon fiber-reinforced epoxy matrix composites. Results showed that the nanofiber interlayer increased the amount of work achieved and the maximum force in quasi-static punch shear experiments. It also contributed to the composite material properties in quasi-static indentation and short-beam shear tests. The enhanced mechanical properties make these composites more reliable for aerospace and automotive applications.

Summary: In this study, an anisotropic damage model is used to simulate the fracture pattern of Bohus granite under quasi-static spherical indentation loading, with good agreement between numerical simulation results and experimental data. The research suggests that indentation test results can be used to calibrate the statistical distribution of tensile strength at small size scales.

Summary: This paper proposes a strain rate dependent formulation of the latent heat evolution for SMA wires in order to improve the accuracy of existing macroscopic modeling approaches, particularly for dynamic load cases. The proposed formulation, validated through cyclic tensile tests, shows more accurate predictions of wire response compared to the strain rate independent formulation. The formulation is successfully applied in simulation of multi-story frame structures incorporating multiple SMA wires, with shaking table tests confirming the accuracy of the responses under different excitation conditions.

Summary: This study investigated the cyclic behavior of glass-FRP reinforced precast high-strength concrete tunnel lining segments. The experimental findings revealed that the GFRP-reinforced HSC PCTL segments exhibited stable hysteretic response until failure. The results showed that the GFRP-reinforced HSC PCTL segments were able to achieve adequate ductility indexes as well as deformability limits.

Summary: The study applied the acoustic emission method to investigate the damage and failure mechanism of carbon/glass fiber-reinforced hybrid laminate composite specimens during tensile experiments. The post-processed AE signals were found to correlate with different damage modes identified by Micro-CT imaging, demonstrating the reliability of AE signals for composite structure health monitoring.

Summary: Waste tires are a severe environmental threat worldwide. Adding crumb rubber to epoxy resin can effectively enhance the mechanical properties of the material, especially the flexural modulus and strength. The stress-strain curves show different fracture strains and brittle failure behavior at different strain rates. The composite with 30% crumb rubber content exhibits the highest modulus and strength.

Summary: In recent years, there has been a significant increase in the interest in sustainability in many industrial sectors. This can be achieved through lightweight design and eco-friendly manufacturing processes. One potential solution to the concerns over the use of non-recyclable thermoset composite materials is to replace the thermoset matrix with a recyclable or renewable matrix, such as a bio-based resin. Experimental tests have shown that composites made with bio-based resin have similar mechanical properties to those made with epoxy resins, making them a reliable substitute that reduces the carbon footprint.

Summary: This study investigates the mechanical behavior of glass fiber reinforced polymer single-lap adhesive joints under quasi-static cyclic loading. It examines the effects of z-pinning and adhesive thickness on the strength and stiffness of the joints. The experimental results show that using single-lap joints with 16 z-pins enhances the ultimate load under monotonic loading. Thinner adhesive thickness results in higher ultimate load but lower shear stiffness with the same number of z-pins. Under quasi-static cyclic loading, 16 z-pins and 1 mm adhesive thickness significantly increase the ultimate load and number of cycles the joint can tolerate, reducing stiffness degradation and displacement increment.
