Summary of Results
In the fiber bundle model schematic of an abalone nacre interface, each of the fibers is modeled using a WLC model. Each fiber has a random number of modules, which unfold at random thresholds. Whenever a module unfolds, the persistence length of the fiber changes thereby changing its WLC response.
The numerical response results of the fiber bundle model is generated using a Worm-like Chain fiber code. Fifteen fibers were used as input, which resulted in a maximum unfolding force of 420 pN, which is in good agreement with the experimental response diagram.
