Finite element modeling of grain size effects on the ultrasonic microstructural noise backscattering in polycrystalline materials

•An original FE approach to quantify the ultrasonic noise scattering is proposed.•The use of the reciprocity theorem guarantee the versatility of the approach.•A frequency-dependent ratio is derived between the 2D and 3D noise measures.•Grain size effects on backscattered noise levels in polycrystal...
