Statics and inertial dynamics of a ruck in a rug.

Abstract:

We consider the familiar problem of a bump, or ruck, in a rug. Under lateral compression, a rug bends to form a ruck--a localized region in which it is no longer in contact with the floor. We show that when the external force that created the ruck is removed, the ruck flattens out unless the initial compression is greater than a critical value, which we determine. We also study the inertial motion of a ruck that is generated when one end of the rug is moved rapidly. We show that the equations...
