Hello,
I have a unit cell composed of piezoelectric particle and non-piezoelectric polymer matrix as shown in the image below. I want to calculate the EFLX (Electric flux density) vector. I am using Abaqus. I have used 3D stress element for the matrix and piezoelectric element C3D4E for the particle. I have applied zero displacement boundary conditions (BC) normal to all surfaces and zero electric potential BC on all surfaces except Z+ surface. If you look at the image the EFLX field is generated only in the particles and read zero in the matrix. Now I think the electric field should be propagated throughout the whole unit cell which means it should not read zero in the matrix. I think I am missing the bonding or contact BC at the interface of the particle and matrix. I would appreciate any suggestions on how to fix the problem.
