Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: In order to meet the diversified requirements for polymer-based composites in modern electronic devices and electrical systems, the simultaneous enhancement of thermal-electrical-mechanical properties is a great challenge. The gradient structured composites, designed by adjusting the distribution of temperature, electric and stress fields in polyethylene (PE) based composites with different Al2O3 contents, demonstrated superior through-plane thermal conductivity, high breakdown strength, and good tensile strength. Finite element simulation provided evidence for the action mechanism on gradient structure regulating temperature and electric field. The strategy of constructing gradient structure provides a feasible route to meet the comprehensive performance requirements of PE based composites in massive manufacture scenario for practical insulation applications.

Summary: The aggregation of nano-carbon fillers in composites due to van der Waals forces hinders their excellent conductive properties. To overcome this, a dispersion strategy using phenyl glycidyl ether (PGE) as a non-covalent functionalization agent was proposed.

Summary: This study focuses on the functionalization and distribution of conductive fillers, as well as the interfacial compatibilization of polymer blends, in order to improve the electrical conductivity and electromagnetic interference shielding efficiency of composites. By modifying the carbon nanotubes (CNTs) with an ionic liquid copolymer and controlling the blending process, selective localization of CNTs at the interphase and the formation of effective conductive networks at the interface were achieved. This resulted in a significant increase in electrical conductivity and a maximum EMI shielding efficiency of 41 dB for the PLA/PCL/PIL/CNT composites.

Summary: This paper investigates phenomena associated with microstructure and how the main deformation mode can be controlled through a second gradient parameter. The results demonstrate that by increasing the second gradient parameter, the deformation mode can switch from shear to one with a constant curvature along the specimen. By studying two different geometries of fibrous composite reinforcements, it is shown how the effects of local bending stiffness of the yarns can be taken into account in a homogenized way in a homogeneous second gradient continuum.

Summary: This study investigates the creep behavior of wooden structures using a combination of numerical modeling and experimental studies. Uni-axial tests were conducted to calibrate the constitutive law and identify the elastic parameters of the spruce species. Three point bending tests were performed to determine the creep parameters of compressed and uncompressed spruce wood. The results of the bending tests were used in an inverse problem with the numerical model to obtain the viscous parameters. The behavior of laminated beams made of uncompressed spruce boards assembled with compressed spruce dowels was also analyzed, leading to interesting findings.

Summary: This article proposes a theoretical numerical model to predict patient dependent osteoporotic bone degradation. The model parameters are identified through a particle swarm optimization algorithm and based on individual patient high resolution peripherical quantitative computer tomography (HRpQCT) scan data. The degradation model is based on cellular activity initiated by the elastic strain energy developed in the bone microstructure through patient's body weight. The macro and meso scale analyses are carried out and compared with in-vivo experimental bone degradation for four elderly women over a period of 10 years, showing a significant correlation and low average deviation error. The model can be easily extended to other patients and provide accurate predictions for different population categories.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
