Generalized plane strain deformation of multilayer structures with initial strains

A closed-form solution for multilayer structures with initial strains under generalized plane strain conditions is presented. Such solutions can be useful for estimating the curvature radius and strains or stresses for self-positioning microand nano-structures with lattice mismatched layers. Comparison with finite element results shows that the developed solution predicts reasonable values of the curvature radius at the central part of the structure. Strains provided by the generalized plane strain solution are in agreement with those obtained by finite element analysis. a) Journal of Applied Physics, 100, 113518-1–4 (2006) b) Electronic mail: [email protected]
