英文摘要: When measuring plate specimen deformations, traditional two-dimensional (2D) digital image correlation (DIC) often leads to insufficiently accurate results due to out-of-plane motion of the specimen during the measurement. To remove the effects of out-of-plane motion, a compensation method for 2D DIC has been developed by researchers. The method markedly improves 2D DIC measurement accuracy. However, two problems with this compensation method remain to be solved: (1) the compensation-method coefficient matrices are affected by experimental noise and correlation errors, and (2) the coefficient matrices are singular when the specimen deformations are small enough, especially when the specimens remain static. For these reasons, an improved compensation method is proposed in this paper. The...
