摘      要：Figure 1 Effective dielectric constant of a sim ple tetragonal lattice with spacing d in the Z direction and w in the X and Y direction as a f unction of spacing/radius(d/R) at constant volume fraction (f).Full circ les indi cate the result of dipole approximation and open circles are from the extended R ayleigh identity. Figure 2 Calculated stress,in units of Pascal,plotted as a func tion of strain i.e.,the title angle θ as defined in the *** parameters us ed in the calculation are εp/εf=5.0,E=2.0 kV/mm,f=0.2,and RM/R=0.985. Figure 3 Shear modulus G vs applied electric field E0 .Solid l ine indicates the shear modulus of the new ideal ER system and the dashed line s hows that of the traditional one (RM=0). Figure 4 Shear modulus G divided by εf vs ε p/εf for v arious thickness of dielectric coating,RM/R=0.985(open circles) and RM /R=0.955(full circles).
