Abstract Scope |
Micromechanical modeling and simulation can be employed to investigate the relationships between microstructural features such as shape, size and distribution of fibers and damage initiation and propagation. Such capability could be extremely essential to develop constitutive laws at the appropriate length scale and to explore damage mechanisms for designing damage tolerant materials. However, the microstructural modeling and simulation predictions must be validated against micromechanical testing data. This study presents peridynamic and Regularized eXtended Finite Element Method (RxFEM) predictions and their comparison against test data concerning micropillar composites with continuous fibers under transverse compression. The micropillar specimens made of IM7/977–3 present debonding and matrix cracking during transverse compressive loading. The PD and RxFEM models are constructed by utilizing the actual topology of fiber reinforced composite micropillars with two different fiber orientations. These models can help understand basic knowledge of microstructural instabilities, effects of nanovoids, interfacial deboning and matrix cracking in the development and design of future composite systems |
