| Summary: | a much greater effect than positive R ratio fatigue loading an excellent manner under static and fatigue loading. and computationally determine the static and fatigue response composite sandwich panels under direct tension and damage initiation and propagation under static and fatigue depot level repair. The simplicity of the overlap over the endurance of the panels. The scarf repair demonstrated a fatigue tests. Both methods of repair proved to perform in for two methods of repair to an E/Glass-Epoxy sandwich global effects of damage observed during the static and i-methods, however, proved to viable options for field and laminate. The proposed methods of repair are a scarf and loading. It also provided excellent agreement with the methods of repair. Computational models were constructed, Negative R ratio fatigue loading, however, was found to have on the initiation and propagation of damage and the overlap patch. A series of tests was carried out on square performance of the repaired panels was compared against rectangular sandwich panels under four-point flexure. The repair for both positive and negative R ratio loading. Both repair. scarf patch make it a more practical option for field level slightly higher endurance to fatigue loading than the overlap subroutine accurately predicted the mode and location of The objective of this research program is to experimentally the structural integrity of a repaired panel. The material to model damage initiation and propagation and its effects on undamaged panels to establish a baseline comparison for the which incorporated a non-linear material response subroutine, |
