Question about the critical stress for fracture in abaqus
(OP)

For example, I use the ball to press the glass beam, I know the critical stress of fracture for glass is about 70Mpa. So that means every node what I measure must small than this critical stress(70Mpa)? So just like the photo shows, the max., mid. and min. Principal stress must small than 70Mpa? But the Abs. of min. Principal stress is always very high, have no ideas why min. Principal stress so high. Thanks very much!

Your mesh is not suitable for this, both element type and refinement. Use C3D8R for this, with much smaller element size especially near the impact location. Also be sure to use spherical contact smoothing for the ball.
