Entwicklung mechanischer Modelle zur analytischen Beschreibung der Materialeigenschaften von textilbewehrtem Feinbeton
… orientated reinforcements in an averaged sense. Microcracks are included by additional strains in the representative volume element. The average interaction between the microcracks and the reinforcements is considered by an effective field approximation. As a criteria for the initiation of the …

Microcracking Fracture Toughness for Graphite Epoxy Composite Laminates Using Finite Fracture Mechanics
… current study was undertaken to determine the microcracking fracture toughness in composite laminates using the energy release rate criteria. Three materials of specific interest in the aerospace industry – IM7/977-2, IM7/5555 and IM7/5276-1 – were analyzed. To evaluate the microcracking …

Investigation of Microcrack Growth in [0/90]s Graphite Epoxy Composite Laminates Using X-Ray Microtomography
… and this research concentrates on study of microcracking, delamination and other defects in the [0/90]s composite laminates of the above materials. These materials were uni-axially tested to pre-determined stress levels and the damages in the material were recorded in the form of microcrack …

Fracture process zone : microstructure and nanomechanics in quasi-brittle materials
… microscopy investigations suggested increased microcracking near FPZ regions, and increased microcrack density with decreased grain size. Ultimately the study provides four contributions to the study of fracture of quasi-brittle materials: an algorithm for the automatic assessment of …

The Effect of Long-Term Thermal Cycling on the Microcracking Behavior and Dimensional Stability of Composite Materials
The effect of thermal-cycling-induced microcracking in fiber-reinforced polymer matrix composites is studied. Specific attention is focused on microcrack density as a function of the number of thermal cycles, and the effect of microcracking on the dimensional stability of composite materials. …
