摘要： Detection, identification, and monitoring of various composite-damage types such as impact damage, delaminations, etc. using angle-beam coupled guided waves and methods and systems that permit excitation with angle-beam techniques of certain composite-material guided-wave modes that cannot be excited in isotropic metals with angle-beam methods.
