Abstract:

A method of virtual displacements is developed for obtaining the transient or steady state behavior of electromechanical systems which may include piezoelectric crystals and magnetostrictive material. This method involves the association of a number of electric current modes and mechanical displacement modes with generalized coordinates, and gives a set of equations, one for each mode, which resembles the mesh equations of a lumped network. A reciprocity theorem is derived, which is applied to a sonar transducer, and which is of fundamental importance in the calculation of sonar target return. Author
