Summary: The objective of this study is to verify Puck's failure criterion for multiaxial mechanical loading situations in ambient and cryogenic thermal regimes. The study concludes that Puck's criterion provides conservative results in most cases. Unresolved additional safety margins may develop when a structural failure requires larger delaminations between adjacent plies.

Summary: This study proposes a simple method to embed different failure criteria into the phase field model (PFM) to calculate fracture timing and direction. By introducing an activation parameter to control fracture timing and a structural tensor to reflect fracture direction, the proposed PFM enforces fracture evolution direction in line with the specified criterion.

Summary: Upgraded design standards and natural disasters have driven the development of smart materials to modernize construction practices. This study presents a nonlinear finite element model for evaluating the performance of beam-column joints reinforced with shape memory alloys (SMA) and steel rebars. Through validation and parametric analysis, the optimal use of SMA bars to enhance seismic resistance without compromising energy dissipation capacity was determined. The simulation results showed that SMA bars, when used with steel reinforcement, effectively improved the seismic performance of the joints, with high-strength concrete being the most influential parameter.

Summary: Energy accumulation and release are typical characteristics in the deformation process of layered rocks. This study investigates the anisotropic properties and energy evolution of layered shale samples through uniaxial compression tests. The results show that the mechanical properties and failure modes of layered rocks exhibit anisotropy, and the energy reserve of the rock mass is also anisotropic. Energy evolution is dominated by accumulation before peak strength, followed by dissipation and release. The elastic-dissipated energy ratio decreases slowly in the elastic stage and increases significantly after the peak fracture stage with a mutation point. A strength failure criterion based on energy mutation is proposed for the prediction of layered rock strength under uniaxial compression.

Summary: This paper presents a novel model for predicting energy dissipation in composite laminates during out-of-plane loading, based on experimental observations of damage mechanisms and their sequences. The energy dissipated during fiber breakage was found to be approximately 3 times larger than that for delamination propagation. The first damage mechanism observed during out-of-plane loading was matrix cracks and induced delaminations.

Summary: This study demonstrates that low expression of Dachshund homolog 1 (Dach1) in type II alveolar epithelial cells (AECII) contributes to the progression of pulmonary fibrosis (PF). Dach1 deficiency exacerbates PF in mice, while overexpression of Dach1 alleviates lung damage and fibrosis. Mechanistically, Dach1 represses epithelial apoptosis by binding to the promoter of B-cell lymphoma 2 interacting mediators of cell death (Bim), thus preventing PF development.

Summary: Despite many efforts in tuning catalytic performance of metal-organic frameworks (MOFs) through modification of MOF nodes, steric tuning of MOF nodes via ligand modification remains challenging. In this study, two two-dimensional Cu(I) cyclic trinuclear unit (Cu-CTU)-based MOFs with similar structures, named JNM-1 and JNM-5, were successfully synthesized. JNM-5 exhibited higher crystallinity, porosity and chemical stability, but lower catalytic activity for hydroboration reactions compared to JNM-1. However, JNM-5 showed higher substrate selectivity and chemo-selectivity for hydroboration of olefins.

Summary: This study integrates a plate-type local resonator with varying free boundaries within a plate to convert the initial low-order global vibration modes into localized vibration modes. A novel semi-analytical method is proposed to analyze the free vibration of the plate with thickness and displacement discontinuities. The results show that by applying free boundary conditions, the low-order localized vibration frequencies can be significantly reduced without affecting the low-order global frequencies.

Summary: In recent years, there has been an increasing number of studies on the mechanical properties of sandwich structures manufactured with the Fused Deposition Modeling (FDM) method. However, there is still a lack of experimental data on the mechanical characteristics of FDM-manufactured sandwich structures under different thermal aging durations. In this experiment, the energy absorption capabilities of sandwich structures with different core geometries were investigated under various thermal aging durations. The results showed that the core topology significantly influenced the energy absorption abilities of the sandwich structures.

Summary: This paper presents a series of experimental and numerical studies on the performance of a novel double-stage coupling damper (DSCD). The effects of damper configuration, friction-yield ratio (Rfy), and loading protocol on the hysteresis performance of the DSCD are investigated. The test results demonstrate that the arrangement of ribs in the DSCD increases its energy dissipation capacity. Numerical analysis reveals that the length of the friction mechanism and the clearance between the yield segment and the restraining system affect the energy dissipation and stability of the damper.

Summary: The structural response of water-back plate under the combined action of shock wave and bubble loads at water depths of 1-300 m was numerically investigated using an arbitrary Lagrange-Euler method. The accuracy of the numerical model was validated by comparing with experimental and theoretical results. The influences of water depth and length-to-diameter ratio of the charge on the combined damage effect were analyzed. The results show that as water depth increases, the plastic deformation energy of the water-back plate decreases, and the permanent deformation mode changes from convex to concave. When the charge has a large length-to-diameter ratio, the plastic deformation energy of the radial plate is higher than that of the axial plate, and the difference decreases with increasing water depth. Increasing the length-to-diameter ratio enhances the combined damage effect in the radial direction in deep-water environments.

Summary: This paper investigates the flexural performance of CFS zed section members bent about the neutral axis parallel to the flanges through experimental and numerical analysis. The results show that the current direct strength method generally provides conservative predictions for the flexural strength of unstiffened zed section members, but slightly unconservative design for edge-stiffened zed section beams. The nominal flexural strengths of zed section members with edge stiffeners were found to be underestimated by 17% to 21% on average. Modified DSM formulae are recommended for the design of CFS zed section beams.

Summary: This research investigates the mechanical properties of high-strength ring groove rivet assemblies and the load resistances of riveted T-stubs. Experimental tests reveal that Grade 10.9 rivets have higher yield strength and strain, and lower ultimate strain, making them suitable for high-strength ring groove rivet connections. Increasing the rivet diameter benefits the T-stubs, while increasing the flange thickness is not always advantageous. The Eurocode 3 method is not suitable for T-stubs connected through ring groove rivets, while the Demonceau method is conservative.
