Abstract:
1. An ultrasound system for measuring axial material properties of material using ultrasound, the ultrasound system comprising: an ultrasound transducer assembly providing at least one ultrasonic transducer for: (a) transmitting an ultrasound signal into the material along a first transverse direction perpendicular to an axial extent of the material and receiving the ultrasound signal after reflection and modification by the material to obtain a first and second echo signal from a first and second material location when the material is at a first and second tension applied along the axial extent of the material; and (b) transmitting an ultrasound signal into the material along a first oblique direction at an angle between the transverse direction and the axial extent of the material and receiving the ultrasound signal after reflection and modification by the material to obtain a first and second echo signal from the first and second material location when the material is at the first and second tension applied along the axial extent; and a processor receiving the first and second echo signal from the ultrasound signal along the transverse and oblique directions and processing the signals according to a stored program to determine at least one of axial stress and axial stiffness of the material.
