Summary: In this paper, a semi-decoupled marker and cell (MAC) scheme is proposed for the Stokes-Biot system, which separates the displacement of the structure from the whole system using a time-lagging scheme. The remaining system composed of velocity and pressure is treated similarly to the Stokes-Darcy coupling problem. The scheme preserves desirable qualities such as mass conservation. The stability and error estimates for the fully discrete scheme are derived, showing second order superconvergence for the discrete L-2 norm of velocity, pressure, and displacement, as well as some terms of the H-1 norm for displacement and velocity. Numerical experiments confirm the theoretical analysis results and parameter robustness.

Summary: In this paper, pressure-correction schemes based on marker and cell (MAC) method for the linear Stokes-Biot system with a fixed interface are proposed and analysed. The implicit backward Euler scheme is used for time discretization, with the coupling terms treated explicitly. These computationally efficient schemes solve two decoupled problems and require solving one vector-valued elliptic equation and one scalar-valued Poisson equation per time step for the Stokes equations. They have optimal order without the incompressibility constraint and are proven to be unconditionally stable, as demonstrated by numerical experiments.

Summary: This study investigates the influence of the host matrix on the photothermally driven actuation performance of DASA-based polymers. By designing polymeric materials with varying DASA incorporation, the relationships between material composition and physical, mechanical, and photoswitching properties are examined. Results demonstrate the importance of designing a material that is stiff enough for mechanical strength required for actuation, yet soft enough for reversible switching, providing key considerations for application-oriented photoswitchable materials.

Summary: Grafting modification is an effective method to enhance the electrical properties of polymeric materials. However, grafted polymers often face the challenge of large leakage current at high temperatures. In this study, we synthesized an itaconic anhydride grafted polypropylene using the solution grafting method, which exhibited excellent insulation properties up to 120 degrees C. By analyzing the mechanisms, we found that the grafted itaconic anhydride restrained free electrons through strong electrostatic attraction, preventing charge injection and transport. We also identified intramolecular forces, deep energy traps, and fragmentized spherulites as key factors contributing to the superior high-temperature electrical properties of grafted polymers. This research provides valuable insights into the charge transport mechanisms in grafted polymers and their impact on insulation characteristics, which is crucial for designing polymeric materials with exceptional electrical properties.

Summary: This study developed an integrated approach to evaluate the groove depth effect on water depths and skid resistance on runway pavement. The results showed that smaller groove depth led to thicker water film depth and smaller friction coefficient. The non-uniform distribution of water film depth caused different skid resistance encountered by aircraft tires and increased safety risk of landing. The developed simulation approach can help determine the threshold of groove depth for maintenance treatment.

Summary: This study investigated piezoelectric cantilevers for energy harvesting using multi-physics modeling. The can-tilevers with multiple degree-of-freedoms (DOFs) were designed to match multiple-frequency vibrations of structures. By adjusting the cantilever design, resonant frequencies in a wide range of 5 Hz-35 Hz can be achieved, potentially fitting the vibration scenario of a typical bridge structure. The maximum voltage outputs or power outputs remained the same level, respectively at 30 V or 5 mW, with no extra coverage area required from the multiple-DOF cantilever.

Summary: This study developed a numerical modeling approach to analyze the impact of sea level rise (SLR)-induced groundwater rise on coastal pavements. The model considered the unsaturated characteristics of subgrade soil and non-linear distribution of moisture content. The results were validated using field tests. The critical responses of pavements were evaluated based on realistic moisture content data. The groundwater table and subgrade soil type were found to be two factors impacting the pavement responses under SLR scenarios. The compressive strain on the subgrade increased more significantly than tensile strains at the bottom of the asphalt layer under the impact of SLR.

Summary: This study aimed to develop and evaluate vibration-based piezoelectric energy harvesters for generating power from bridge structures. New designs of multiple-degree-of-freedom cantilevers were proposed and evaluated in the laboratory and on a full-scale bridge. The potential of generating 35 V voltage outputs was found in all cantilever designs under a simple sinusoidal vibration scenario in the laboratory. Furthermore, field testing results showed that the match between the vibration frequencies of the bridge structure and the resonant frequencies of the cantilevers significantly affected the voltage output of the piezoelectric energy harvester.

Summary: This study proposes a microstructure model based on real aggregate shape and digital image technology to predict the permeability coefficient of concrete. A two-dimensional, three-component finite element model was established, considering the interfacial transition zone (ITZ) between aggregate and mortar, and a prediction model for the permeability coefficient was developed using the finite element method. Experimental data verified the accuracy of the model and the influence of the water-cement ratio on the permeability coefficient was analyzed. The results show that the method has good prediction accuracy, with a relative error of 1.73%. The study also explores the effects of aggregate content, characteristics, location, ITZ thickness, and other factors on the permeability of concrete. The water-cement ratio, aggregate content, and aggregate characteristics were found to significantly affect the permeability coefficient, while the roundness of the aggregate, aggregate size, and ITZ thickness also had noticeable influences.
