The heterogeneous and anisotropic nature of fiber reinforced polymers induces the initiation of various damage mechanisms at different scales. Even though full-field surface measurements may successfully track damage development, such approaches do not provide insights into the material bulk. The present work aims at comparing surface and bulk full-field measurements (via Digital Image/Volume Correlation) for a comprehensive analysis of polymer composite damage. Bulk measurements revealed that damage initiated at the microscale, thus contributing to surface localization phenomena. Full-field surface measurements could not capture the local strain states that the constituents were subjected to, which led to final fracture.

纤维增强聚合物的异质性和各向异性性质导致在不同尺度上引发各种损伤机制。尽管全场表面测量可以成功跟踪损伤发展，但这种方法不能提供对材料体积的洞察。目前的工作旨在比较表面和整体全场测量（通过数字图像/体积相关），以对聚合物复合材料的损伤进行综合分析。批量测量显示损伤始于微观尺度，从而导致表面定位现象。全场表面测量无法捕获成分受到的局部应变状态，这导致最终断裂。
