500 years after the first studies on friction, the concepts of superlubricity, wearless sliding and friction control are being realized in laboratories and have become predictable by adequate ...

Join Alemnis' three-day course on tribology to master friction, wear, and lubrication, enhancing the reliability of ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

An important observation is that fluid flow is always irreversible. It is irreversible because fluids have viscosity, and whenever velocity gradients appear in the flow there will be friction and ...

Ice causes very little friction, which is why it is easy to slip over on an icy day. However, this is a good thing for ice skating and sledging. Friction is a force between two surfaces that are ...
