Abstract. New decision of stochastic connected boundary-volume problem of electro-magnetic elasticity by generalized singular approach of statistical mechanical of composites is received on base of the new decisions for singular parts of second derived Green’s function for uniform transversal-isotropic piezo electro-magnetic media. Results of calculation of effective temperature factors and a pyroelectric constant of porous barium titanate for various values of porosity and for some porosity forms are presented.

Key words: piezocomposite, boundary value problem of electro-magnetic elasticity, effective pyroelectric properties.
