We use the theory of continuously distributed dislocations to formulate the static
equilibrium condition for an edge dislocation pileup near a circular elastic
inhomogeneity in terms of a singular integral equation. The singular integral equation
is solved numerically using the Gauss–Chebyshev integration formula to arrive at the
dislocation distribution function and the number of edge dislocations in the pileup. In
our discussion, either the leading edge or the trailing end of the pileup can be located
at the circular interface.
