Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip ...

The dynamic rupture of earthquakes requires a strength loss from pre-slip, static friction to co-seismic, dynamic friction, and so major experimental effort has been devoted to determining fault ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
