Numerical Prediction of Differences in Micromechanical Fracture Sequence in Notched and Un-Notched Wires for Civil Engineering Applications
Abstract: The need to employ
simulation-based investigations of fracture of civil engineering structures has
been emphasised recently in literature. In this paper, three dimensional finite
element simulations revealed that the cup and cone fracture process in
channel-shaped notched wire for civil engineering applications begins with a
slant fracture at the root of the outer edge of the channel-shaped notch and
follows a slant to flat fracture sequence. These results demonstrate that the
fracture origin in cup and cone fracture in notched wires for civil engineering
applications does not necessarily begin with a flat fracture at the center of
the wire and does not necessarily follows the flat to slant fracture sequence
or propagation generally reported in literature. These results further
demonstrate the need to employ simulation-based methodologies in conjunction
with or as an alternative to purely experimental fractographic analysis for an
accurate failure analysis of wires used for civil engineering applications.
