use:
Used to test the elastic modulus of materials, including ceramics, concrete, cement, glass, metals and alloys, plastics and polymer products, rocks, wood, and composite materials. It has a wide measurement range, high accuracy and The feature of convenient operation can simultaneously obtain the dynamic Young's modulus, shear modulus, Poisson's ratio and the elastic properties of the material at different temperatures.
Necessity of the instrument:
Elastic modulus is the most basic mechanical performance index of elastic materials, but the accurate measurement of elastic modulus of materials in the past is time-consuming and laborious. WAD's agent of imported BUZZ instruments broke through this problem in one fell swoop. The principle of the device is to use the material's inherent resonance frequency to measure the material's elastic modulus.
The BUZZ elastic modulus tester uses external excitation to vibrate inside the test piece, uses a collection device to collect the resonance frequency, and then uses software to calculate it. It is fast and convenient. It does not require special sample preparation. It can be used for in-situ testing and is suitable for ceramics. , Concrete, cement, glass, metal and alloy, plastic and polymer products, rock, wood and composite materials and other types of elastic materials.
The accuracy of the resonance frequency measured by the BUZZ elastic modulus is higher than 0.005%, which accurately reflects the properties of the material itself. Various elastic performance parameters can be obtained through software calculations. If auxiliary equipment such as temperature control is added, the samples can also be obtained in different environments. The elastic properties.
The working principle of the equipment:
The BUZZ elastic modulus meter receives the vibration generated by the sample being excited through the sensor, and the vibration signal is recorded in the system through the amplifier, including all the information of the vibration wave, until the vibration fails. The system then displays the final result on the panel through data processing.
Sample detection:
During the test, place the sample on a support that does not affect the free vibration of the sample, tap the sample to excite the vibration, and use vibration or acoustic sensing equipment to collect signals at the corresponding part of the sample. The data of vibration frequency can be read directly on the display screen of the host, and data such as Poisson's ratio can be obtained by inputting the obtained data into the processing software. The shape of the sample can be strip, disc (column) shape. The length of the strip sample should be at least 3 times greater than the width and height to achieve the highest test accuracy. The ratio of the diameter to the thickness of the disc (column) sample is at least greater than 4, and the recommended multiple is 10-20
Advancement:
The advantage of the BUZZ modulus of elasticity is that it is convenient to test and does not require special sample preparation. It is suitable for various types of materials such as ceramic concrete, cement, ceramics, glass, metal and alloy, plastic and polymer products, rock, wood and composite materials. , The elastic modulus test range is wider than 100MPa~400GPa, the accuracy is better than 0.005%, and it is stable and reliable.
Practical introduction:
The Young's modulus, shear modulus and Poisson's ratio of the sample can be measured accurately and quickly. The elastic modulus test range is wider than 100MPa~400GPa, covering a wide range of samples, and can be used for various types of materials such as concrete, cement, ceramics, glass, metal and alloy, plastic and polymer products, rock, wood and composite materials. The data repeatability is very good.
The size of the test sample is less required, no special sample preparation is required, and non-destructive testing can be achieved. High and low temperature tests can be performed. Suitable for scientific research and quality inspection fields.
Safety and reliability:
Since the advent of the BUZZ instrument, continuous efforts have been made to improve the convenience of the test method and the accuracy of the results. The company provides customers with a variety of probes, software, equipment and support, which can be used to measure the elastic modulus of various types of materials. Due to its unique and superior performance, in recent years, BUZZ modulus of elasticity has been adopted by more and more research institutions and industrial users all over the world. By the end of 2010, this instrument had more than 1,000 system users worldwide.
