A full 3D, orbit-anywhere stick-slip friction model of a real door hinge, showing how dry metal-on-metal contact excites the hinge bracket's own resonant vibration to produce the creak.

⚙ Under the hood

3D stick-slip friction model of a door hinge — dry metal-on-metal contact winds up and releases, exciting the hinge bracket's own resonant frequency to produce the creak.
