Abstract
Μία μέθοδος η οποία χρησιμοποιείται για την κατασκευή ελεγχόμενων ελαττωμάτων που αντιστοιχούν σε φυσικές ατέλειες και εναπομείνασες τάσεις σε διάφορα είδη δοκιμαστικών κομματιών. Ελαττώματα πανομοιότυπα με φυσικές ατέλειες απαιτούνται για την πιστοποίηση μη καταστρεπτικών δοκιμαστικών (NDT) διαδικασιών. Στην μέθοδο, χρησιμοποιούνται διαδοχικοί, επαναλαμβανόμενοι κύκλοι θέρμανσης ψύξης για τη δημιουργία ελαττωμάτων και εναπομενουσών τάσεων. Το σχήμα του μοτίβου θέρμανσης και ψύξης, η διάρκεια της θέρμανσης και της ψύξης και ο αριθμός θερμικών κύκλων χρησιμοποιούνται για τον έλεγχο του μεγέθους των προσλαμβανομένων ελαττωμάτων και εναπομενουσών τάσεων. Το ελάττωμα αναπτύσσεται χωρίς αρχική ατέλεια ή κάποιον άλλο πυρηνοποιητή. Τα ελαττώματα αντιστοιχούν σε φυσικές ατέλειες σε όρους μορφολογίας και επίσης των σημάτων που προσλαμβάνονται με μεθόδους NDT, και είναι κατάλληλα για χρήση, για παράδειγμα σε κομμάτι πιστοποίησης NDT.
