αβΩ-inclusion sets for general C-eigenvalues of a general piezoelectric-type tensor.

C-eigenvalues and C-eigenvectors of piezoelectric-type tensors play an important role in the piezoelectric effect and the converse piezoelectric effect. In this paper, with the help of components of general C-eigenvectors, we present a new class of inclusion sets to locate all general C-eigenvalues for a given general piezoelectric-type tensor. Finally, numerical examples are reported to be tighter than some existing results. [ABSTRACT FROM AUTHOR]
