Summary: This research experimentally studied the mechanical properties of a hybrid green kenaf-cotton composite laminate and analyzed them using FEM simulations and experimental validation. Tensile tests showed delamination, while bending tests demonstrated good flexibility of the composite structure. Simulation results indicated that the composite thickness directly affected the force applied in flexural tests.

Summary: The movements in two directions of the boundary between twinning variants and matrix were observed for the first time using in-situ electron backscatter diffraction (EBSD) during continuous three-point bending tests in nuclear grade pure zirconium. The mechanism of this movement was proposed based on the combination of schmid factors and the three dimensional model of identified twinning variants, and a new atomic model illustrating the movement of the twinning boundary was suggested.

Summary: The study reevaluates the nonlinear mechanics of three-point bending and four-point bending tests for thin silicon dies, considering geometric nonlinearity and proposing correction factors based on NFEM results. These correction factors, presented as polynomial fitting equations, are proven to be workable and highly dependent on deflection, span length, and radius of roller support, but not on test specimen thickness and elastic modulus.

Summary: A study was conducted on the DBTT and microstructure of various pure tungsten grades and tungsten alloys under neutron irradiation. Potassium doped tungsten alloys exhibited the lowest DBTT, followed by other reinforced tungsten grades. The microstructure and grain orientation were found to significantly impact the DBTT, emphasizing the importance of optimizing manufacturing processes based on grain shape and boundaries.

Summary: This study investigates the load-deflection response of the material used for production of polymeric pipes, evaluating their flexural properties and examining the effects of various configurations and parameters. The research shows that the flexural stress-strain response of pipe materials exhibits distinct characteristics and behaviors under different loading conditions. Aging and notches significantly decrease the flexural performance of pipe materials.

Summary: The bending properties of cardboard in different directions were studied using three-point bending and elastica bending tests with various span lengths. The bending stiffness, moment at the proportional limit, and moment capacity per unit width were determined. The results showed that the bending stiffness decreased as the span length decreased, especially when the sample's length direction coincided with the machine direction. However, the moment capacity decreased when the length direction coincided with the cross direction due to large deflection.

Summary: The study develops an analytical method to extract the homogenized tensile properties of a cell from bending tests and utilizes this data to calibrate a material model for pouch cells. The model is used to build a finite element pouch cell model that can predict the load-displacement, shape of deformation, buckling wavelength, and failure trend in complex crash scenarios.

Summary: This study presents the influence of stress state on the drivers of non-classical twin nucleation in three-point bending of Magnesium alloy AZ31. Deformed microstructures and textures at the tensile and shear regions are investigated in detail. Experimental observations coupled with strain-gradient crystal plasticity analyses reveal that shear nucleates more twins compared to tensile and compressive stress states at near yield-point.

Summary: Incorporating carbon nanofibers in intelligent concrete has negligible influence on crack initiation toughness, but increases the instability toughness initially and then decreases as the fiber content increases. At certain fiber contents, carbon nanofibers significantly improve the crack initiation toughness and ductility of intelligent concrete.

Summary: The paper proposes a new method that takes into account the number and location of the fibers when estimating the postcrack performance for a cracked cross section in a three-point notched bending beam tests. Although the proposed method is more complex and requires more effort than the existing method, it provides more repeatable material parameters, which exhibited a higher characteristic result.

Results showed that DTN had higher compressive stiffness in the best-case surgical scenario, while MDTP performed better in the worst-case scenario.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

We propose new regression equations that consider soft-tissue thickness, sex differences, and a height-directional measure, and validate them using leave-one-out cross-validation.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
