Ultrasonic tensile stiffness method The tensile stiffness index of the paper and board can be measured without destroying the sample by using ultrasound. But this method is not a standardised measuring method and it does not give exactly the same results as a tensile stiffness test made with a tensile tester. The modulus of elasticity
