  The strain incompatibility equations are discussed for nonlinear
Kirchhoff-Love shells with sources of inhomogeneity arising due to a
distribution of topological defects, such as dislocations and disclinations,
and metric anomalies, such as point defects, thermal strains, and biological
growth. The incompatibility equations are given for all topological surfaces,
with or without boundary, which are isometrically embeddable in a 3-dimensional
Euclidean space.
