We initiate a study of homeomorphisms f with constant principalstrains (cps) between smoothly bounded planar domains D, D′. An initial result shows that in orderfor there to be such a mapping of a given Jordan domain D ontoD′, a certain condition of an isoperimetric nature must besatisfied by the latter. Thereafter, we establish the fundamentalfact that principal strain lines (characteristics) of suchmappings necessarily have well-defined tangents where they meet∂D. Using this, we obtain information about the boundaryvalues of the Jacobian transformation of f, and finally wedetermine the class of all cps-homeomorphisms of a half-planeonto itself
