Abstract

Physics-Informed Neural Networks (PINNs) offer an effective model of solving coupled multiphysics equations in biomedical polymer composite systems, which are data-driven. In the given work, the PINN method is presented where equations of elasticity, mass diffusion, and heat transfer are integrated to model the complex processes that take place in composite biomaterials. The neural network loss is specified to include the governing partial different equations which enables both the system responses and the physical behavior to be learned at the same time. The proposed structure reduces the use of the massive experimental data and ensures consistency on the physical level. Compared to conventional numerical methods, numerical data can be more accurately predicted and those that are based on standard numerical methods are more predictable and stable, which proves that PINNs are a potentially valuable tool to work with new biomedical materials and optimize their design. It has been demonstrated in the paper that Physics-Informed Neural Network is useful in simulating coupled multi-physics physics in biomedical polymer composite systems. The combination of the process of elasticity, heat transfer and diffusion in one learning model allows the proposed method to be very accurate, stable as well as computationally efficient unlike the traditional methods. The fact that the PINNs can enforce the physical law, and no longer depends on large datasets is what makes them particularly suitable in more complex biomedical problems. Subsequent research will be done on scaling, time-dependent, and nonlinear behavior framework, experimental validation, and scaling, which will allow real-time analysis and design of advanced composite materials in biomedical applications.
