Teaching Period (valid 01.08.2018-31.07.2020):
Learning Outcomes (valid 01.08.2018-31.07.2020):
After the course the student can:
-Apply the physical fundaments of the main NDT techniques;
-Identify the variants of the main NDT techniques;
-Select the NDT techniques and main operational parameters for different industrial applications;
-Interpret with criteria the results from inspection;
-Identify the most common and critical defects from the general industrial applications;
-Predict the morphology, localization and dimension of the defects considering the type of material and manufacturing techniques.
Content (valid 01.08.2018-31.07.2020):
Non-destructive testing (NDT) has a number of important roles to play in ensuring the through-life quality and reliability of many important products whose integrity is of paramount importance. The traditional role of NDT in quality control during manufacture - predominantly defect detection - has been complemented in recent years with increasingly important inspections in-service on plant and equipment at varying stages through life. The correct application of NDT can prevent accidents, save lives, protect the environment and avoid economic loss.
NDT and inspection are vital functions in achieving the goals of efficiency and quality at an acceptable cost. In many cases, these functions are highly critical: painstaking procedures are adopted to provide the necessary degree of quality assurance. The consequences of failure of engineering materials, components and structures are well known and can be disastrous.
In the present course the students will review the physical fundaments of the main NDT techniques and will be presented to the most relevant variants of the conventional NDT techniques. Focus will be given to the establishment of the morphology, localization and dimension of the defects typical in many engineering materials and resulting from the application of several manufacturing techniques.
