Camellia oleifera shell (COS) mechanical-structural property and cracking behavior are crucial for hulling, hulling work can improve the extraction oil quality. A developed texture analyzer with in situ observation is built for COS mechanical-structural and crack testing. Influencing factors are studied under working effects, considering fruit size, drying temperature, compression distance, speed, directions. The shell compression damage is analyzed with compression damage model. Results show that COS compression damage can be divided into three stages: shell elastic deformation, initial crack...
