Non-destructive testing of elastic modulus and Poisson's ratio Ultrasonic measurement method1 ScopeThis standard specifies the ultrasonic measurement method of material elastic modulus and Poisson's ratio based on the sound velocity method, including personnel, equipment, samples, procedures and reports Complaint and other requirements. This standard is applicable to the detection of the elastic modulus and Poisson's ratio of metal and non-metal solid materials. Other composite solid materials can also be used by reference.2 Normative referencesThe following documents are essential for the application of this document.

Note. As shown in Figure 1a), the points B1, B2, B3 and B4 in the half-wave detection signal are the signal front; as shown in Figure 1b), the points in the bipolar detection signal R1, R2, R3 and R4 are the signal leading edges. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38897-2020_English be delivered?Answer: Upon your order, we will start to translate GB/T 38897-2020_English as soon as possible, and keep you informed of the progress.
