dc.description.abstractTherepair technique of the composite patch with bonding adhesive are used with thepurpose of repairing materials and increasing working life of the materials. Inthis study, the impact strength of notched metal materials repaired bycomposite patch investigated by numerically. Fiber reinforced laminatedcomposite patch was modeled by using finite element model. Composite patch wasbonded to damaged materials, and this structure was subjected to impact test. Thegeometrical and material non-linearities were considered in the explicitdynamic analysis. The notched plate was made of aluminum 6061-T6. The effects ofdesign parameters, such as composite patch geometry, on the impact energyabsorption of the plates were investigated. The metal notched plates weremodeled as a Johnson-Cook material model and the composite patches were modeledorthotropic elastic material model and Hashin damage. In the analysis results,the damage mechanisms of composite patch were exhibited and strength of damagedmaterials was exhibited in terms of contact force, kinetic energy and stressdistributions. The effect of patch geometries was also investigated in terms ofabsorbing impact energies. As the plates without patch perforated, repairedmetal notched plates with composite patch did not perforate.
