Using the simplified 3D DIC method to measure the deformation of 3D surface

摘要：

　　In recent years,2D digital image correlation method (DIC) has been widely used in the measurement of plane strain.However,out-of-plane displacement could be induced during the loading and it would affect the measurement accuracy.Thus,a 3D measurement is necessary.This study utilizes a simplified 3D DIC to measure the geometry of an object before and after deformation.Then the finite element concept is involved to determine the strain after deformation.A fiat plate specimen with in-plane and out-of-plane displacement is observed.Both 2D and 3D DIC are used to analyze the strain.The results show that using 3D DIC to measure strain is feasible and with a very good accuracy.
