An Octahedral Fibrous Constitutive Model for Heart Valve Mechanics and Function
Nishan Parvez, Prashant K. Purohit, Wensi Wu
Fibrous soft tissues derive their nonlinear mechanical response from networks of extracellular matrix fibers, whose organization gives rise to strain stiffening, the reverse Poynti…

A Physics Preserving Neural Network Based Approach for Constitutive Modeling of Isotropic Fibrous Materials
Nishan Parvez, Jacob S. Merson
We develop a new neural network architecture that strictly enforces constitutive constraints such as polyconvexity, frame-indifference, and the symmetry of the stress and material…
