1. 1. Further development of moulding technology for underwater applications in nuclear reactors

   Uppsats för yrkesexamina på avancerad nivå, Materialvetenskap

   Författare :Hanna Nygren; [2010]
   Nyckelord :moulding; non-destructive evaluation; nuclear; polymer compound;

   Sammanfattning : To be able to ensure quality, efficiency and safety in nuclear reactors, non-destructive evaluations (NDE) are performed. The moulding technique, which has been studied in this project, is an NDE method used to verify surface breaking cracks at various objects in reactor vessels. LÄS MER

3. 2. Crack Detection using Non-linear and Dissipative Acoustics

   Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Daniel Carldén; Daniel Thuresson; [1998]
   Nyckelord :Non-linear acoustics; Non-linear parameter; Burger s equation; Bessel-Fubini; Fay; Mendousse; Hedberg; Non-destructive testing NDT ; Non-destructive Evaluation NDE ; crack detection.;

   Sammanfattning : A theoretical model for identification of acoustical non-linearity using Burger's equation was implemented in a MATLAB program. The program identified both the non-linearity parameter and the distance from the signal source. Tests were performed in order to verify the theories. LÄS MER
