Foldable Mac Hinge & Crease Mechanics
Direct mechanical simulation of Apple's water-drop hinge geometry, panel tension distribution, and ultra-thin glass (UTG) stress.
Angle: 180° (Flat)
Stress: 21.4 MPa (Nominal)
Hinge Internal Bend Radius
4.5 mm
Tight Fold (2.0mm)
Water-drop Neutral (4.5mm)
Relaxed Arc (8.0mm)
Foldable Mode Orientation
