THEOREM OF WORK RECIPROCITY FOR PYROELECRIC ELASTIC MEDIA WITH APPLICATION

With the linear elastic theory,theory of dielectrics and thermal conduction theory,the equations of work reciprocity similar to Bett’s theorem of work reciprocity are derived for pyroelectric elastic media.According to the equations,the pyroelectric elastic Somigliana’s boundary integral equalities were presented, which can be widely applied to boundary element method.
