Özet:

 


 The
repair technique of the composite patch with bonding adhesive are used with the
purpose of repairing materials and increasing working life of the materials. In
this study, the impact strength of notched metal materials repaired by
composite patch investigated by numerically. Fiber reinforced laminated
composite patch was modeled by using finite element model. Composite patch was
bonded to damaged materials, and this structure was subjected to impact test. The
geometrical and material non-linearities were considered in the explicit
dynamic analysis. The notched plate was made of aluminum 6061-T6. The effects of
design parameters, such as composite patch geometry, on the impact energy
absorption of the plates were investigated. The metal notched plates were
modeled as a Johnson-Cook material model and the composite patches were modeled
orthotropic elastic material model and Hashin damage. In the analysis results,
the damage mechanisms of composite patch were exhibited and strength of damaged
materials was exhibited in terms of contact force, kinetic energy and stress
distributions. The effect of patch geometries was also investigated in terms of
absorbing impact energies. As the plates without patch perforated, repaired
metal notched plates with composite patch did not perforate.
