Gecko Peel-Front Fracture Kinetics (2D)

Interactive 2D model of gecko-adhesive peel dynamics: set an applied peel force and angle and watch the delamination front obey real crack-tip fracture kinetics, with the classic Kendall peel force emerging as the threshold at which the front starts moving at all.

A gecko toe pad releases from a surface the same way any thin adhesive film does: Kendall's peel equation, F/b = Γ/(1 − cos θ), sets the force per unit width needed to make the delamination front move at all. This 2D model puts the applied peel force directly under your control and lets the front's actual position emerge from a crack-tip fracture-kinetics rate law rather than from a pre-set kinematic sweep — set F below the Kendall threshold for the current angle and geometry and the array stays locked indefinitely no matter how long you wait; push it over the threshold and the front accelerates the harder you exceed it. Watch the live energy release rate track against the Kendall critical force, and see the discrete seta row flip from shear-locked green to released red exactly where the crack tip has passed.

⚙ Under the hood

Set an applied peel force and angle on a 2D gecko-adhesive model and watch the delamination front obey real crack-tip fracture kinetics: the front stays locked below Kendall's critical force Γ/(1-cosθ) and accelerates once the energy release rate exceeds it.
