The present study aimed to develop and validate a transversely isotropic finite element (FE) model of the cranial suture that predicts suture mechanics, validated using ex-vivo data from the swine internasal suture. A 2D displacement-controlled FE model of the bone-suture-bone complex was constructed using microcomputed tomography (μCT) images, with a uniform cross-section and boundary conditions replicating experimental tensile tests. Suture geometry was modeled at three evenly spaced positions to explore how mat…
