Abstract

The article is considering by applications of electronic speckle pattern interferometry (ESPI) in the composite materials industry. The use of composite materials in various construction elements has substantially increased over the past years. These materials are widely used in situations where large strength-to-weight ratios are required. This paper collects some information about possibilities, advantages, and disadvantages of ESPI applications by nondestructive testing of composite materials and briefly introduces a damping feature of composites. Theory of plate vibrations allows us to determine Poisson's ratio V , Young's modulus E and shear modulus G from the measured resonant frequencies. We are able to analyze the damping behavior of various types of composite materials from measured mode shapes.
