Brief bio of Hans Ansell
Hans Ansell has been employed by Saab AB since 1978. He is Technical Fellow since 1998 in structural integrity and specifically in the area of structural fatigue and damage tolerance. Hans has worked with structural integrity issues such as regulations and rules for implementation, development of methods and procedures for sizing and testing of military aircraft such as JAS39 Gripen versions and technology studies of these as well as with unmanned aerial vehicles e.g. UCAV Neuron and civilian aircraft such as Saab 340/2000.
 
  • Has developed and implemented systems for loads and service life monitoring of Gripen. 
  • Has participated in the majority of life extension programs for J35 Draken, AJ/JA 37 Viggen, SK60 and others and in incident investigations, several service life and accident investigations.
  • Participated as expert in the several of Gripen's export businesses regarding structural integrity issues of the customers.
  • Has been line manager for development of stress and strength methods, material data and load sequence handling and is the area manager for structural analysis at Saab Aeronautics.
  • He is Certification Verification Engineer for approve of structural repairs of Saab340/2000.
  • Has participated in national R&D programs like NFFP and international R&D programs such as EU, Garteur and NATO/AGARD/RTO.
  • Has been Sweden’s national delegate since 2005 in ICAF, the International Commission on Aeronautical Fatigue and Structural Integrity. 
  • Adjunct professor in the area of fatigue and damage resistance since 2015 at Linköping University, Department of Solid Mechanics.
  • Supervisor of Industrial PhD students in the field of structural integrity of hybrid metal and composite structures as well as fatigue properties of additive manufactured aircraft applications.

UTMIS är ett ideellt nätverk för företag, institut och universitetsinstitutioner med syfte att inom utmattningsområdet verka för:
 • informations- och kunskapsspridning
 • ökat samarbete
 • kompetenshöjning
 • projekt som utvecklar området
 • att påverka forskningsråd och stiftelser

 En målsättning är att genom att framföra gemensamt formulerade behov, öka satsningen på utmattningsrelaterade områden i första hand på nationell nivå.

 UTMIS arbetar dessutom för ett starkare internationellt samarbete i utmattningsfrågor. Bland annat är styrelsen för UTMIS samtidigt nationell organisation för ESIS (European Structural Integrity Society).
