本研究的目的是验证当前和 提出的复合材料细观力学模型的直接实验 测量，并确定附近产生的应力状态 材料中受到拉伸、压缩和 弯曲载荷 这将通过独特的测试来实现 该方法采用了一个几何放大版本的一个 含有嵌入式传感器的聚合物复合材料。 这些传感器 提供了一种直接和系统的方法来测量应变 在材料中重新分布，并提供以前无法获得的 基线数据是验证现有模型所必需的， 开发新的。

The objectives of this research are to validate current and proposed composite micromechanical models by direct experimental measurements and to determine the resulting stress state near damaged regions in materials subjected to tensile, compressive, and bending loads. This will be accomplished with a unique test methodology which employs a geometrically scaled up version of an polymeric composite containing embedded sensors. These sensors provide a direct and systematic approach to measure strain redistribution in a material and provides previously unobtainable baseline data which are essential in validating existing models and developing new ones.
