Abstract:
This study investigates friction phenomena in bioprinting and material interactions, focusing on gelatin-based systems. A novel analytical and numerical model is presented, investigating the relationships between sliding velocity, relaxation time, and tangential stress. The model's application to gelatin highlights its two-component structure and its significance in tribology. Computational outcomes are validated against Baumberg, Caroli, and Ronsin's experimental data, showcasing consistency. This research enhances comprehension of friction mechanisms in bioprinting and material science, offering insights into intricate physical and chemical interactions. The study underscores the utility of advanced modeling in deciphering complex tribological processes and their broader applications.
