Abstract:
As the field of Microstructure Sensitive Design (MSD) advances within
materials science, increasing detailed models become available to
describe the various states and properties of materials. However, these
models still support the traditional approach of performing a physical
experiment followed by measurement of the results. While this method is
effective in gathering data and furthering development of these models,
it does not substantially extend the design capabilities of materials
engineers.
The material property closure is a tool used by MSD engineers in order
to evaluate the possible property combinations of various
microstructures of a given material. By treating individual data points
within the closure as nodes, a logical network topology can be
constructed of subset(s) of points within a given closure. These nodes
are linked by the material deformation processes used to derive them
from their parent point, with the exception of a user selected initial
point.
In this thesis, a software module is developed to derive and overlay
these network relations on an existing closure plotting application.
The module also contains an integrated database component in order to
store computed network topologies for later reconstruction and
analysis. By building simple networks defined by a relatively small
number of material processes, the amount of the closure covered by the
network and its various rotational analogs can be determined and
analyzed. In addition, the use of a shortest path algorithm on the
network topology demonstrates routability within the closure space as a
precursor to end-to-end process design between two distinct property
combinations.
