Abstract

The work aims to realize the non-contact testing of paper elastic modulus based on digital image correlation method and controlled speckle printing technology. Because the paper was a printable material, the high quality speckle pattern designed and fabricated could be printed on both ends of the gauge distance of the sample paper by the printer. In the uniaxial tension process, the linear strain of the gauge was measured by digital image correlation method, and the elastic modulus of the paper could be calculated by linearly fitting the strain value with the stress value obtained by the stretcher. In the proposed method, three samples with longitudinal modulus of elasticity of 80 g/m2 kraft paper was tested, and the average test value was 1900 MPa. Based on the reasonable design of the simulated image parameters, the paper possesses high quality speckle pattern and the effect of the print ink on the mechanical property of the paper is the least. The proposed method is applied to measure elastic modulus of the kraft paper. The deviation of the measured results of three samples is small, which proves the good reliability of the proposed method to some extent.
