Summary
he aim of the subject is to present to the auditorium the state of the
evaluation of defectoscopy of material. First of all the ability to form the
defects in material will be shown. The natural content of defects will be
compared with the posibility to detect and to evaluate the critical defect size
in the structures. The start of the evaluation proces is concentrated on the
surface defects. There the main possibilities are the penetration method and
the magnetic metod. Also the eye observation is not so incorrect. Then,
the through body raditation methods are comming into account. The ultrasonic
techniques are exelent and very usefull in this case. Further, the other
technics are comming into the consideration. For the thinner products the X –
ray radiation is relevent, for thicker products the finer (and more expensive
methods) are available. We touch the radiation of shorter wave size as the
β-
radiation and the γ – radiation. In conclusion, the basic fracture
mechanics
is introduced as well as the application of fracture mechanics to the
evaluation of defects in material.
