Persistence Market Research
Acoustic Emission refers to the production of transitory elastic waves produced due to the sudden re-distribution of stress and strain in a material. When the material is subjected to extra stimulus, such as change in temperature, load or pressure, energy release is triggered in the form of stress waves. These stress waves propagate towards the sensors that record them. Using the right equipment setup, waves on the order of 10-12 (Pico meter) can be recorded.
The study provides market analysis with reference to services side of the market which is commonly referred as acoustic emission based NDT market hereafter. Acoustic emission testing is a non-destructive testing technique. In this technique, instead of supplying energy to the specimen, the sensors listen and record the energy waves released by the specimen. Detection and analysis of acoustic emission signals supplies valuable information with respect to the origin and the importance of discontinuity in the material. Also, acoustic emission based non-destructive testing deals with the dynamic changes in the material, thus highlighting only the active features and flaws, such as crack growth, in the material. This provides an ability to distinguish between stagnant and developing defects which, in turn, drives the acoustic emission based NDT market. The versatility of acoustic emission testing enables the process to find industrial applications, such as monitoring weld quality, testing for leaks, detecting flaws and assessing structural integrity. Also, acoustic emission based NDT is finding applications in the petrochemical and manufacturing industries which propels the acoustic emission base NDT market.
However, acoustic emission based NDT systems can only gauge qualitative features of how much damage is contained in the structure. This kind of non-destructive testing cannot provide the quantitative results (with respect to depth, size and overall acceptability of the specimen). Also, acoustic emission testing cannot function efficiently in noisy environments that contribute extrinsic noise to the signals. These factors challenge the growth of the acoustic emission based NDT market.
The trend of miniaturization has impacted the acoustic emission based NDT market heavily. As the testing is undertaken at different industries and different locations, the demand for miniaturized and portable testing equipment is on the rise. For instance, the acoustic emission based NDT equipment for oil and gas sector is required to be light in weight and compact in order to inspect specimen at locations that are tough to access.
