Extended Data Fig. 4: Finite element modelling.
a, FE mesh with 180,384 CPS4R elements and 16,308 COH2D4 elements. b, FE predictions of the stress distribution in sBIN gels with NB grafting degree of 0.7 (left) and 2.1 (right) when they ruptured. Both of their Rw values were set to 0.20. The FE predictions indicated that the stronger interface led to higher fracture strength of the BIN gels. A widely accepted hyperelastic model (Ogden model) was adopted.
