1. A method for detecting various types of damage in composites comprising:
employing at least one adjustable angle beam transducer to achieve single-mode guided wave excitation by generating a shear horizontal (SH0) wave excited into at least one quasi-isotropic composite via intrinsic shear coupling present in the at least one quasi-isotropic composite;
observing wave propagation and interaction within a test subject;
and detecting damage in the test subject; and
employing at least two different modes of wave propagation to detect and identify different types of damage, wherein the method can separate detection of delamination from impact damage other than delamination including matrix cracking and fiber breakage to the test subject.
