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 ...

In the automotive sector, test standards are an important factor where clutches, brakes, tires, engines, seatbelts, etc. are checked for their material properties to comply with a number of standards ...

• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...
