Abstract
Studies of flexural motions of lithosphere commonly apply a differential
equation based on the thin-plate approach. In this approximation, the
flexural response to a changing horizontal inplane force depends only on
the curvature of the midplane of the thin-plate representing the
mechanical behaviour of the lithosphere. However, in cases where an
abrupt change of the geometry of the lithosphere occurs the midplane of
the thin-plate is offset. We demonstrate that the combination of the
offset with an inplane horizontal force produces an additional, rheology
independent moment at the position of the geometry change. This effect
has been overlooked by,previous studies of lithosphere deflections, and
thin-plate problems in general. In the presented analysis, the
thin-plate with an abrupt change in plate geometry represents
lithopshere with a mechanically healed, inactive fault. However, the
derived analytical solutions are,general and can be used to study
problems with similar abrupt geometry changes.
