摘要: 本文利用MATLAB的2D数字图像相关程序Ncorr对生物材料——野猪牙齿的位移场和应变场进行了分析。通过高清摄像头，拍摄获取了野猪牙齿在受外力前、受微小外力作用后的数字图像。通过Newton-Rapshon算法确定两组数字图像中心点的位移情况，并对野猪牙齿在微小外力作用下的位移变化和应力应变进行了分析。最后，通过对数值计算结果的分析，给出了某些具体位置上的位移和应力变化情况，为研究野猪牙齿提供了有关理论依据。
Abstract: In this paper, the displacement field and strain field of biomaterial-wild pig teeth are analyzed by MATLAB’s 2D digital image correlation program Ncorr. Through the high-definition camera, the digital image of the wild boar teeth before being subjected to external force and subjected to a small external force was obtained. The displacement of the center points of the two sets of digital images was determined by Newton-Rapshon algorithm, and the displacement changes and stress strains of the wild boar teeth under the action of tiny external forces were analyzed. Finally, through the analysis of the numerical calculation results, the displacement and stress changes at some specific positions are given, which provides a theoretical basis for the study of wild boar teeth.
