Group Description
Welcome to [NDT Inspection Portal]’s acoustic emission (AE) group, a place for professionals to connect and discuss the latest techniques and technologies in AE.
Acoustic emission (AE) is a specialized field within non-destructive testing (NDT) and inspection that involves the detection and analysis of acoustic waves or vibrations emitted from materials or structures as a result of internal or external stimuli. It is an important aspect of ensuring the safety and reliability of components, structures, and materials in various industries, including manufacturing, construction, and engineering.
Acoustic emission (AE) involves the use of specialized sensors and equipment, such as piezoelectric transducers, to detect and analyze acoustic waves or vibrations emitted from materials or structures. It may involve the use of other NDT methods, such as ultrasonic testing and radiographic testing, to identify any potential issues or defects, such as cracks, porosity, or corrosion. AE is often used to monitor the integrity and performance of components, structures, and materials in real-time and to predict potential failures or issues. It is particularly useful in situations where it is not possible or safe to physically access the inspection site or to apply load or stress to the material or structure.
Our member group offers a platform for sharing knowledge and best practices on AE and its applications in various industries. Join our community of experts from around the world and be a part of the conversation on advancing the practice of AE and its applications in the field of NDT and inspection. Whether you are new to AE or an experienced professional, you’ll find valuable resources and a welcoming community in our group.

I find this work interesting. In this work can we say that we are measuring the lamb wave?charlie replied 1 year, 4 months ago 2 Members · 1 Reply- 1 Reply
(Dear Sir,
The classic definition of Acoustic Emission (AE) refers to the generation of transient elastic waves in the form of stress waves.
These stress waves can be originated from deep in the components (other than the pipes) having considerable thicknesses and are propagated in all directions. Eventually they reach the surface and can travel several meters and are picked up by the sensors.
When they reach the surface and propagate they can certainly be treated as Lamb waves but not very sure before they reach the surface from several centimeters from inside the component.
Best wishes
