The response of a semi-infinite plate bounded by a straight edge and excited harmonically by a stud attached to its edge is presented in terms of an admittance matrix that relates the two in-plane rotatory velocities and the transverse velocity of the stud to the respective forces. The problem is solved by means of the classical theory of thin plates and by assuming a simple stress distribution along the plate edge. Numerical results for stud widths smaller than one-third of the flexural wavelengths and for a value of Poisson's ratio σ=0.3 are given. They are found to relate well to known results for the full infinite plate.
