Residual stress measurements on a metal matrix composite using the contour method with brittle fracture Conference or Workshop Item

  title={Residual stress measurements on a metal matrix composite using the contour method with brittle fracture Conference or Workshop Item},
  author={Jeferson Oliveira and Michael E. Fitzpatrick and Jan Kowal},
In this work we evaluate the application of the con tour method to fatigue and fracture surfaces. Residual stress measurements were made on quenched and aged AA2124-SiC p composite using neutron diffraction, the contour method with wire E DM, and the contour method on a fatigue crack surface including brittle failure. The contour meth od successfully measured residual stresses from a wire electro-discharge cut surface, but the fractur e method results suggest that residual stress information is… CONTINUE READING
