Aluminum honeycomb sandwich structure material has been widely used in aviation

aerospace

construction industry and some other fields.The honeycomb core is a structure mainly composed by hollow areas

of which strain should be diffucultly tested by the traditional electrometry.The digital image measurement is firstly applied in the research on the tensile tests of aluminum honeycomb core by CCD.The force-displacement curve in the whole tensile process is obtained and corner detection is used to obtain Young’s modulus and poisson ratio in linear elastic stage which are compared with the calculated values according to the theory on Y honeycomb core equivalent models.It provides references for research on the mechanicl properties of whole honeycomb sandwich structure and structure design.
