文摘

A 3D virtual model was developed to simulate compression responses of tomatoes. Pericarp tissue was meshed into elements whose size approximated tomato cells. Internal damage volume of fruit was evaluated quantitatively by FE simulation. A sigmoidal function relates the damage volume to the compression force. Tiny damage of fruit at the microscale began from the start of the compression.
