We show that a sufficient condition for the weak limit of a sequence of W1q-homeomorphisms with finite distortion to be almost everywhere injective for q ≥ n−1, can be stated by means of composition operators. Applying this result, we study nonlinear elasticity problems with respect to these new classes of mappings. Furthermore, we impose loose growth conditions on the stored-energy function for the class of W1n -homeomorphisms with finite distortion and integrable inner as well as outer distortion coefficients.
