چکیده
Strengthening the fundamental understanding of micromechanical methods in continuity is a critical aspect developing and designing future composite systems. Virtual testing has provided additional behavior materials on microstructural scale. However, experiments must be executed to determine their validity. Modeling realistic microstructures under loading conditions could help develop physically based constitutive laws needed predict intrinsic failure. In this study, micropillar with varying sizes was manufactured out continuous fiber reinforced composites transversely compressed observe phenomena. The shape, size, distribution were recorded as well stress vs strain curves for each size micropillar. specimens speckled perform 2D digital image correlation (DIC) analyze displacement contours surface. results from study provides basic knowledge instabilities, effects nanovoids, interfacial debonded matrix crack formation while transverse compressive loading.
