Document Type: Journal Paper
A layered system composed of a linear viscoelastic layer and linear elastic supporting foundation is considered—the layer being described by a classical thin plate and the foundation as a homogeneous half space. Disregarding inertial effects, a formal solution is obtained for arbitrary time-dependent surface tractions. As an example, the special case of a concentrated load moving with constant velocity is examined. The solution is expressed in terms of known elastic results plus time-dependent correction terms. Bounds obtained for these correction terms indicate they are negligible for large values of the dimensionless velocity, as defined by the writer.
