Abstract Scope |
Biological tissues are critical materials in the structure and function of living organisms. The accurate characterization of mechanical properties of biological materials is vital for comprehending the healthy functioning of tissues and diagnosing diseases. However, the hierarchical and composite nature of biological tissues results in nonlinear, heterogeneous, and anisotropic mechanical behavior that making it challenging to accurately characterize their mechanical properties. In this work, a physics-informed convolutional neural network (PICNN) is developed to construct the structure-mechanical property relationship between the local microstructure and the bulk mechanical properties of the tissue. The PICNN is able to accurately predict the stress-strain curves under three tension and three compression modes. Moreover, the PICNN can predict the bulk mechanical properties of the tissue by adding the Holzapfel-Ogden constitutive model as the physical constraint. The proposed PICNN model is general and can be utilized on various fibrous composite structures and tissues. |
