【摘要】 本文提出一个简便的,用多火花动光弹仪进行动态变形测量的白光散斑方法,用此方法不但可以进行动态大变形测量,也可动态小变形测量。如果和动光弹等色线结合,可以同时获得被测材料的弹性模量、泊松比、材料条纹值参数。更多还原

【Abstract】 This paper presents a simple method for measurements of dynamic deformation by mismatch white speckle method using dynamic photoelastic device. The method can be used to measure not only large dynamic deformation[1], but also small dynamic deformation. By combining with dynamic isochromate pattern, the elastic modulus, Poisson’s ratio and dynamic material fringe value of the material measured can be obtained by the method.更多还原
