基于拉伸试验过程中应变场的数字图像相关分析，研究了由脆性钢和韧性钢组成的多层复合材料的变形动力学。在复合材料的长度尺度上，在均匀截面试样的拉伸试验期间，局部化带传播。在单层的长度尺度上，观察证明，当整合到复合材料中时，马氏体相可以承受超过20%的非局部拉伸应变。
The deformation kinetics of a multilayered composite made of brittle and ductile steel layers is studied based on the strain fields obtained from digital image correlation during tensile testing. At the length scale of the composite, a localization band propagates during tensile testing of a uniform section specimen. At the length scale of the single layer, observations proved that the martensitic phase can withstand non-localized tensile strains of more than 20% when integrated into the composite.
