PRODUCT DETAILS
- DETERMINATION of Young’s Modulus and Ultrasonic Velocity in solids like metals/quartz/glass
- Non-Destructive Testing of Material is an important part of Engineering Education as it gives information without deformation in the shape and size of the material. One of the NDT techniques,
- Piezoelectric Technique is widely used for the measurement of composition dependent properties such as ultrasonic velocity, compressibility, elastic constant, Young’s Modulus and Bulk modulus. Its suitability for metals, plastics, polymers and crystals etc makes it versatile tool for Engineering Physics, Material Science and Polymer Science. -
- This low cost NDT apparatus is being used in several I.I.T.s/Universities/Engineering Colleges for laboratory experiments and Research work.
- In this technique the specimen is cemented to a quartz rod of identical cross section and resonant frequency (fc) of the composite system is determined using the apparatus.
- The resonant frequency of the quartz rod (fq) is also determined. From the knowledge of fq, fc and the masses of the quartz (mq) and the specimen (ms), the resonant frequency of the specimen fs is evaluated using the predefined relation
- INSTRUMENT: It consists of Piezoelectric Oscillator, power supply, quartz rod, holder, quartz
rod with sample, connecting cables and R.F. meter.
