PHILSM and STAUTXFEM variable cloud charts of high elastic stress absorption band along the crack section direction when reaching 7010 times. (a) PHILSM variable cloud chart. (b) STAUTXFEM variable cloud chart. (Note. The green part in (a) represents the crack surface. The red part in (b) indicates that it has been cracked while the light green part indicates that it is near to being cracked.)
