The development of techniques that evaluate changes on vibration parameters appeared as a way for estimating damage on complex structures, since the dynamic response of a system depends on the stiffness and damping local properties. Such structures include those that are built using composite laminate plates, widely used by the aeronautical and automotive industries. Typically, laminates are very sensitive to impacts from foreign objects such as hailstones or mishandled tools, leading to unsafe failures. To assess (detect, locate and quantify) damage in composite materials is still a challenge, especially if a large amount of sensors or expensive equipments are not available. In this article, a low-cost technique that solves an inverse problem making use of vibration-based parameters and adequate computational tools for damage location in laminates is presented. © Civil-Comp Press, 2010.
