For the strength analysis of unidirectional laminae an unit cell approach is illustrated. The unit cell is modeled with an approximate voxel mesh instead of a conventional mesh. Strengths are determined with continuum damage mechanics. A fracture energy formulation is applied to alleviate mesh dependency in the softening behavior. For direct loads the unit cell shows good capabilities for the p...

This paper demonstrates the effectiveness of parametrically-upscaled continuum damage mechanics (PUCDM) models for multiscale analysis S-2 glass fiber/SC-15 epoxy matrix composite beams subjected to single-edge notched bending (SENB) tests. The SENB experiments with [012/9012] double-ply and [08/908/08] triple-ply use synchrotron X-ray phase-contrast imaging in-situ characterization. PUCDM repr...
