Change in strength during cracking of the ball and cracking and bursting

The raw ball is mainly linked by the capillary force of water and has a certain strength. As the drying process progresses, the capillary water decreases and the capillary shrinks. The capillary force is strengthened to increase the compressive strength of the green ball. Whe
