Desenvolvimento de dispositivos para estudo de fratura interlaminar modo-I e modo-II de materiais dissimilares.

Abstract

The main objective of this dissertation for the devices that can be used for mode-I and mode-II interlaminar fracture test in dissimilar materials. For the development of devices for design methodology that projects in informational design, conceptual design, preliminary design, detailed design, fabrication and testing. The choice of the tests that can be used to obtain such fracture modes was made based on the study of academic papers, which pointed to the double beam cantilever (DCB) test, as being the most used for the study of interlaminar mode-I, and end-loaded split (ELS) for the study of mode-II interlaminar fracture. The developed devices were tested in a weight drop impact machine, where aluminum / epoxy adhesive joints were used. Testing and analysis of the behavior of the devices and test bodies were carried out during and after the test.
