“…BaTiO3 (BT)-based piezoelectric ceramics are widely regarded as one of the candidates for lead-free piezoelectric ceramics due to their superior piezoelectricity. Wang et al [31] studied the BT-based ceramics' (1 − x)[(Ba 0.94 Ca 0.06 ) (Ti 0.92 Sn 0.08 )]-xSm 2 O 3 -0.06 mol% GeO 2 (abbreviated as (1 − x)BCTS-xSm-0.06G) comprehensive electrical properties. They proposed that the material obtained optimized piezoelectric properties under the condition of 3 kv/mm (non-180 • domain switching under high polarization electric field).…”

In this paper, the calculation method of dynamic stress concentration around piezoelectric ceramics containing regular n-sided holes under the action of electroelastic coupling wave was studied, and it was applied to promising barium calcium zirconate titanate material. First, electroelastic governing equations were decomposed by using the auxiliary function method, and the solution forms of the elastic wave field and electric field were obtained by using the wave function expansion method. Then, the triangular boundary was simplified to a circular boundary using the mapping function, and the corresponding modal coefficients were determined according to simplified boundary conditions. Finally, the dynamic stress-concentration factor was calculated to characterize the dynamic stress concentration. We performed numerical simulations with a correlation coefficient of (1 − x)[(Ba0.94Ca0.06) (Ti0.92Sn0.08)]-xSm2O3-0.06 mol% GeO2 (abbreviated as (1 − x)BCTS-xSm-0.06G). The numerical calculation results show that the incident wave number, piezoelectric properties, shape parameters of the hole, and deflection angle have a great influence on the dynamic stress around the defect, and some significant laws are summarized through analysis.
