This issue presents research aimed at addressing challenges in engineering, biomechanics, medicine, and geophysics. One study analyzes the effectiveness of computational fluid dynamics (CFD) in predicting flow behavior in pipes with diameter reductions, showing high accuracy compared to theoretical models. In the field of materials science, the mechanical performance of polypyrrole, a conductive polymer with potential biomedical applications, is characterized and compared to that of unmodified PLA. Another article proposes a two-dimensional dynamic system designed to reduce the kinetic energy transferred to a child’s body during vehicular accidents, with possible application for children with bone degenerative diseases. In the geotechnical field, the impact of fluid inclusions on seismic wave propagation is examined, revealing how water, air, and oil alter wave speed and amplitude. Lastly, a low-cost biaxial testing device is designed and validated for evaluating biological tissues, highlighting its precision, safety, and accessibility for studies in laboratories with limited resources.
