An improved virtual material based acoustic model for contact stiffness measurement of rough interface using ultrasound technique
Huifang Xiao,Yunyun Sun +1 more
TL;DR: In this paper, an improved acoustic model based on virtual material is proposed to provide an accurate measurement of interfacial contact stiffness using ultrasound, where the rough interface is assumed to be a thin layer of virtual material to incorporate the effect of ultrasound attenuation at the interface.
