Description
Summary:The problem of excitation of spatially developed Lamb waves by a system of body and surface loads is formulated and completely solved by analytical methods. Using the direct and the inverse Hankel transforms, relations are derived for determining the amplitude factors of radially propagating non-axisymmetric Lamb waves excited by a system of body and surface loads in an arbitrary region of an isotropic elastic layer. Relations for calculating the displacement components of particles of the elastic layer in far field are obtained.
