To characterize the mechanical properties of thin films,an improved blister method is proposed,which combines a digital speckle correlation method with the blister *** on this method,an experimental setup is developed to measure Young’s modulus,residual stress,and interfacial adhesion energy of an electroplated nickel *** results show that the improved blister method has the advantage of a high accuracy full-field measurement with the simple operation and low requirement on environments,which can be used to characterize the mechanical properties of films with various scales from laboratorial to industrial applications.
