A method for modeling textile structures using bicontinuous surfaces includes selecting a virtual scaffold of bicontinuous surfaces defining textile fabrication pathways to model spatial relationships between the pathways and yarns in a desired yarn pattern of a textile fabric design. The method further includes constructing a yarn pathway across the bicontinuous surfaces that form the virtual scaffold. The method further includes removing or releasing tension from the virtual scaffold, thereby allowing yarns to relax and determining a physical property of the textile fabric design.

Topology optimization for modeling and prediction of complex fabric structures and properties

Provided are intraoperative devices, the devices comprising a substrate having a plurality of discontinuous cuts formed therein, the plurality of discontinuous cuts being formed such that when the substrate is subjected to deformation, the substrate is capable of deformation beyond an initial state so as to achieve a first shaped three-dimensional state. Through design of the cut patterns in 2D, one can locally control the stretchability and elasticity within the substrate. The substrate can then be deformed into a 3D structure that can provide shape and support to reconstructed tissue in the desired regions while also minimizing operative time and cost. Also provided are related methods of using the disclosed devices; the devices can be used in autologous tissue donation procedures as well as prosthetic procedures.
