摘要： This paper presents a simple method for measurements, of dynamic deformation by mismatch white speckle method using dynamic photoelastic device. The method is able to measure not only large dynamic deformation[1], but also small dynamic deformation. Combined with dynamic isochromatepattern, the elastic modulus Poisson’s ratio and dynamic material fringe value of the material measured can be obtained by the method.

关键词: finite element, hybrid method, zero energy-error, coarse-mesh-accuracy
