粒状材料在载荷反向时的行为尚未完全了解。为了从实验上揭示加载-卸载循环下试件的微观结构，在X射线扫描仪上对扁豆进行了三轴压缩试验。在分析所获取的断层图像之前，进行基准分析以验证用于从这些图像中提取织物的图像分析工具。在对扁豆的实验中，接触组构随着剪切而强烈演化。然而，只有非常轻微的变化的各向异性的周期内观察到。
The behaviour of granular materials upon load reversal is not yet fully understood. In order to experimentally reveal the microstructure of a specimen subjected to load-unload cycles, a triaxial compression test on lentils is carried out in the x-ray scanner. Before analysing the acquired tomographies, a benchmark analysis is conducted to validate the image analysis tools that are used to extract the fabric from these images. The contact fabric evolves strongly with the shearing in the experiment on lentils. However, only very slight changes of the anisotropy within the cycles are observed.
