| 摘 要： | This paper presents a simple method for measuremts of dynamic deformation bymismatch white speckle method using dynamic photoelastic device.The method is able tomeasure not only large dynamic deformation,but also small dynamic deformation.Combined with dynamic isochromate pattern,the elastic modulus Poisson’s ratioand dynamic material fringe value of the material measured can be obtained by themethod.
