Dynamic Mechanical Analysis of Microstructures

这个应用需要一种动态机械分析仪(DMA)，在这种分析仪中，样品在几种不同变形模式中的一种受到周期性应力。分析了力、位移幅值和相移随温度、时间和频率的变化。为此，DMA配备了一套样品夹持器，可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。该工具在-190C-600C的宽温度范围内工作，在0.001-300HZ的宽频率范围内工作。它提供的相对湿度在5%-85%的范围内，测量室也可以填充特定的气体或混合物。当样本被浸入特定的流体中时，浸没选项允许对材料进行角色化。

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.
