由于节省材料方面的要求越来越高,要求在接近其强度极限范围内充分利用材料。一种构件的使用价值及其由此而具有的可靠性是以无缺陷的材料为前提的。缺陷探测(探伤)和缺陷测量(损伤测定)方面的材料无损检验新工艺在持续发展。可以借助广泛的损伤分析或者(和)断裂机理的计算分析进行损伤构件寿命预测来评定缺陷的信息得到加强。为此,其前提条件是车辆和设备维修中构件无损检验方法的 Due to the ever-increasing demands for material savings, it is desirable to make full use of the material close to its strength limits. The use value of a component and the reliability it possesses are based on a defect-free material. Non-destructive testing of materials for defects detection (flaw detection) and defect measurement (damage determination) The new technology continues to evolve. The information to assess defects can be enhanced by extensive damage analysis or computational analysis of (and) fracture mechanics to predict damage to component life. To this end, the prerequisite for the maintenance of vehicles and equipment components NDT methods
