Two Cases of Inclusion-Inclusion Interaction in a Ti Alloy.

Abstract

A basic investigation was conducted to study the behavior of a continuous media with interacting inclusions. Material property data used for this study modeled an Alpha/Beta titanium. Finite element simulation of the media included a generalized von-Mises yield criteria for plasticity. Uniaxial loading was considered with the parametric variations of the angle between the line of the inclusions and the load direction. Further three boundary displacement restrain conditons were considered. From these analyses the strain localization of the inclusion interaction was examined. The Final Report contains the analyses output data and computer plots of the region experiencing plastic strain. This research is continuing under a separate grant to investigate the strain localization at the inclusions and the formation of microcracks. (Author)
