Dynamic Mechanical Analysis of Microstructures

该应用要求一种动态力学分析仪（DMA），其中样品以几种不同的变形模式之一经受周期性应力。力和位移的振幅和相移作为温度，时间和频率的函数进行了分析。为此，DMA配备了一套样品夹持器，用于六种不同的变形模式：三点弯曲、单悬臂弯曲、双悬臂弯曲、拉伸、压缩和剪切。该工具可在-190 ° C- 600°C的宽温度范围和0.001 - 300 Hz的宽频率范围内工作。它提供5% -85%范围内的相对湿度，测量室也可以填充特定的气体或混合物。浸没选项允许在样品浸没在特定流体中时进行材料表征。

This application requests a dynamic mechanical analyzer (DMA) in which the sample is subjected to a periodic stress in one of several different modes of deformation. The force and displacement amplitudes and phase shift are analyzed as a function of temperature, time and frequency. For this purpose, the DMA is equipped with a suite of sample holders for six different deformation modes: 3-point bending, single cantilever bending, dual cantilever bending, tension, compression, and shear. The tool operates over a wide temperature range of -190°C - 600°C and a wide frequency range of 0.001 - 300 Hz. It provides a relative humidity in the range 5% - 85%, and the measurement chamber can also be filled with specific gases or mixtures. The submersion option allows materials characterization while the sample is submerged in specific fluids.
