Struct PiezoElectric 

pub struct PiezoElectric {
    pub compliance: [f64; 4],
    pub d_matrix: [f64; 3],
    pub permittivity: [f64; 2],
    pub name: String,
}

Piezoelectric constitutive model.

Couples mechanical strain and electric displacement via the d-matrix: S = sE : T + d^t : E_field; D = d : T + ε^T : E_field.

Fields

compliance: [f64; 4]

Mechanical compliance at constant E-field [s11, s12, s33, s44] (Pa^-1).

d_matrix: [f64; 3]

Piezoelectric d-matrix coefficients [d31, d33, d15] (C/N = m/V).

permittivity: [f64; 2]

Permittivity at constant stress [ε11, ε33] (F/m).

name: String

Material name.
