| Abstract: | Dynamic characteristic of uniaxially-reinforced composite cantilever sheet was analyzed by the finite difference method in terms of the bend vibration theory of sheet.Static characteristic of the square sheet was determined,as concentrated forces were applied to its four corners.The dynamic(static) measurement of elastic constants in uniaxially-reinforced composite has been presented.As compared with the usual measurement,it has the advantages of simplicity,rapidity,high accuracy and good repetition. |

| Keywords: | uniaxially-reinforced composite dynamic measurement natural frequency elastic modulus Poisson's ratio shear modulus |
