Abstract
Cylindrical friction (CYLF) joints subjected to impact-induced wave (IIW) loading are studied theoretically and experimentally. The system considered consists of a long, straight, cylindrical and linearly elastic rod which is impacted axially at one end by a cylindrical and linearly elastic hammer. A body is attached at the other end by means of a CYLF joint. The conditions are such that the wave propagation is 1-D in the hammer and the rod and can be neglected in the attached body which is therefore treated as rigid. Slip and energy dissipation in the CYLF joint due to IIW loading are determined as functions of three dimensionless parameters which represent the rod-to-hammer length ratio, the mass of the attached body and the static frictional force. In the general case the problem is solved numerically. In the case of a semi-infinite rod the problem is also solved analytically. The agreement between numerical and analytical solutions is good. There is also fair agreement between theoretical and experimental results.
