延性破坏,就是材料经受了过高的应力,超过了它的屈服极限或强度极限,因而产生较大的塑性变形,最后导致断裂。

延[韧]性破坏 ductile failure
Adding 'U' hoops at the two ends and the midspan can avoid peeling the CFRP sheets from the RC beams. It also can obviously improve the fatigue capacity and finally lead to ductility damage.8.
在两端及跨中加U形箍锚固可以保证CFRP加固RC梁不发生碳纤维布剥落破坏,显著提高疲劳性能,最终发生延性破坏。
