Based on the Voronoi cell finite element can also reflect fiber reinforced composites interface to take off the layer and matrix crack propagation of the new cell (X-VCFEM cell)[1]. Combined with the re-mesh strategy and grid dynamic technology, Simulated analysis in different inclusion distribution, interface crack propagation for fiber reinforced composites, the results show that for the model with multiple Voronoi cell, The horizontal tension was the largest; For only a Voronoi cell, The size of the horizontal tension was little change.The result was very important reference value for manufacturing process and engineering application of fiber reinforced composite materials.

The XFEM was used to forecast the sub-interface crack propagation paths of carbon fiber reinforced composites, and the simulation results were compared with the SEM photos. The change of strain energy and damage dissipation energy in this process was also investigated. The results indicated that the existence of fiber had a certain influence on the crack propagation direction. And the structure energy changed along with the crack propagation.

Combined with the re-mesh strategy and grid dynamic technology, Simulated analysis in different angles and different depth-width ratio, interface crack propagation for fiber reinforced composites, the results show that when 0˚< < 90˚, the horizontal tension increases with the increasing; When 90˚< < 180˚, the horizontal tension decreases with the increasing; And when =90˚, the horizontal tension was the largest; the horizontal tension increases with the depth-width ratio increasing. The result was very important reference value for manufacturing process and engineering application of fiber reinforced composite materials.

Interlaminar Crack

This paper presents an investigation of interlaminar crack growth behavior in fiber-reinforced composites subjected to fatigue loading. In the experimental phase of the study, interlaminar crack propagation rates and mechanisms were determined for the cases of various geometries, laminate parameters and cyclic stress levels. An advanced singular hybrid-stress finite element method was used in conjunction with the experimental results to examine the local crack-tip behavior and to characterize the crack propagation during fatigue. Results elucidate the basic nature of the cyclic delamination damage and relate the interlaminar crack growth rate to the range of mixed-mode crack-tip stress intensity factors. The study provides fundamental insight into the problem, reveals several important features of the interlaminar fatigue failure, and should be of practical importance in selection, testing and design of composite materials.
