Summary: This paper proposes a method to quantify the distribution of values of the properties of a woven hemp fabric-reinforced GreenPoxy composite and finds that the variability in these properties is significantly lower at the composite scale and comparable to glass fibre composites. The paper also provides suitable probability distribution laws for these properties, which are important for ensuring optimized and reliable design of plant fibre composite structures.

Summary: This study presents an analytical solution for exploring the behavior of layered viscoelastic gassy sediments under different types of load. Extensive parametric analyses were carried out to investigate the effects of various factors on consolidation and creep processes. The model considers permeability and modulus of elasticity as time-dependent factors to simulate the long term behavior of gassy sediments.

Summary: This paper introduces a new fatigue life prediction methodology for viscoelastic materials that takes into account the creep effect and requires less input data. The model shows good prediction accuracy for materials under different stress ratios and proposes constant life diagrams (CLDs) and the concept of cyclic-creep interaction.

Summary: This paper analyzes the mechanical properties of shales from the Baltic Basin, focusing on the creep strain under variable stress and elevated temperature conditions. The study reveals that the constant differential stress and creep time significantly influence the mechanical properties of shales. In viscoelastic creep tests, the creep strain is over two times larger in the second stage compared to the magnitude in the first stage, while in brittle creep tests, the axial strain in the first stage is two times larger than in viscoelastic creep tests in the second stage.

Summary: This paper presents a study on the long-term behavior of carbon/epoxy composites, examining the interactions between aging in water and constant mechanical loads through experimental and modeling approaches. The results show that a four-parameter Burgers model provides a good fit to the experimental data, indicating the significant impact of water diffusion on the viscoelastic behavior of the materials.

Summary: This study investigates the influence of stress level and hygrothermal conditions on the creep/recovery behavior of high-grade composites made from GreenPoxy, flax, and hemp fibers. The results show that strains increase with applied load and environment severity, with higher time-delayed strains in the creep phase than the recovery phase. Additionally, a stiffening effect is observed during the recovery phase.

Summary: This study qualitatively investigated the contribution of proteoglycans (PGs) to the biomechanical behavior of the canine cranial cruciate ligament (CCL). The results suggest that altering PGs content changes the microstructural organization and viscoelasticity of the CCLs, which may predispose to injury and lead to knee joint osteoarthritis.

Summary: This study investigates the influence of long-term immersion on the hygro-elastic and hygro-viscoelastic behavior of epoxy resin samples through experimental tests and numerical simulations. A model is proposed to simulate the hygro-viscoelastic behavior of the material, and good agreement between experimental and numerical results is observed.

Summary: This study investigates the impact of fibre dispersion on myocardial biomechanical behaviors, including both myofibre and sheet fibre dispersion. The results show that considering both types of dispersion improves the descriptive capability of the strain energy function and enables more accurate stress prediction in cardiac mechanics.

Summary: The linear viscoelastic behavior of polypropylene was studied using theoretical and computational methods, with the FE analysis showing better predictions and lower errors using the Burgers model. The study's novelty lies in predicting creep and recovery behavior of the polymer in the linear viscoelastic regime using FE and theoretical approaches.

Summary: Dielectric elastomers are solid polymeric materials that can deform under an electric field, making them suitable for energy harvesters, sensors, and soft actuators. However, the influence of thermal effects should be considered in their application, as the base materials often show thermal sensitivity that affects their mechanical response.

Summary: The research indicates that flax-based felts have higher metal biosorption capacity than hemp-based felts, especially for the removal of copper ions. Increasing the adsorbent dosage can improve biosorption efficiency, and biosorption capacity remains stable at pH values between 4 and 6.

Summary: The study evaluated the impact of different treatments on the structure and composition of chenevotte, revealing the presence of unfibrillated impurities on the surfaces before any chemical treatment. After treatment, there were increases in crystallinity index, significant changes in chemical composition, and alterations in surface morphology and roughness. The most pronounced changes were observed in the alkaline-treated samples, particularly those treated with KOH.

Summary: This paper presents a new analytical model that takes into account the influence of tilt angle on the identification of a fiber's transverse elastic modulus. The accuracy of this model is demonstrated by comparing its predictions with results from a finite element model. The proposed model can be reliably used to identify the transverse elastic modulus of fibers in SFTCTs with a tilt angle.
