چکیده مقاله
Nowadays composite structures have found many applications in sensitive and crucial industries such as aeronautic, military, and bio engineering due to their individual characteristics These usages have led to more demand for integrity assurance of these structures, in another hand, one of the most important properties of a material is its detectability or in other words their ability to be NDT In this regard, it is essential to have reliable NDE techniques for the evaluation of these structures Conventional NDT methods have some disability in inspecting these materials so that the novel techniques such as optical methods are considered more than before Shearography is a full field, non contact, and high speed method based on laser light in order to inspect composites and polymeric materials In this research, several specimens of carbon fiber reinforced polymers CFRP and carbon fiber reinforced polymers GFRP with different sizes of cracks have been inspected Also, the important parameters of shearography like loading size, shear distance, and direction for both materials have investigated
