Chinese Webinar: "给力”的DMA测量 - 深入剖析DMA测试参数 (May the "Force" be with DMA - Important parameters in DMA Measurement)

Tuesday, September 28, 2021 | 10:00 - 11:00 AM CST (Beijing Time)

动态热机械分析(DMA)测量技术为对样品施加一定频率的振荡力,测量样品的形变响应,以及两者之间的相位滞后,以此获取材料的模量、阻尼、损耗、黏弹性等力学特性及其随温度与时间的变化。该技术广泛应用于塑料、橡胶、弹性体、树脂复合材料、薄膜、纤维、涂层、金属、陶瓷等领域。
对于DMA的使用者,为了获得更好的测试结果,有必要较深入地理解DMA的测试原理、相关校正、及各测试参数的物理意义和作用。本次讲座的内容包含如下三个部分:
1.     DMA 测试原理
2.     DMA 相关校正
3.     DMA 各项测试参数剖析
希望对使用者在实践中用好DMA、获取更可靠的实验数据提供一定的帮助。

Dynamic Mechanical Analysis (DMA) is a measuring technique which applies an oscillation force with certain frequency on sample, then measure the deformation response of sample together with its phase lag, thus to get the modulus, damping, energy loss, visco-elastic and other mechanical properties with its change with temperature and time. This technique is widely used in plastics, rubber & elastomer, resin composite, film, fiber, coating, metal, ceramic and other application fields.
For a user of DMA, to get better test results, it’s necessary to deeper understand the principle of DMA, the calibrations, and the physical sense and usage of various test parameters. So this presentation contains the following three sections:
1.     The principle of dynamic mechanical analysis.
2.     Calibrations of DMA
3.     A study of various test parameters with tips on how to optimize.
Hope this provides help for users in daily work to get more reliable results from DMA.
