Essential effects on the defect-selective heating, such as flaw size, plate thickness, crack mouth opening or static preload, are systematically investigated. Laser vibrometry measurements of the crack edges, theoretical modelling of frictional heating and numerical simulations contribute to the understanding of the involved physics.Technology: general issuesbicsscErmüdungsrissfatigue crackinfrared thermographyInfrarotthermografienon-destructive testingStahlbausteel constructionUltraschallanregungultrasound excitationZerstörungsfreie PrüfungTechnology: general issuesPlum Robin Marcauth1314827BOOK9910346778203321Fatigue crack detection on structural steel members by using ultrasound excited thermography = Erkennung von Ermüdungsrissen in Stahlbauteilen durch ultraschallangeregte Thermografie3032017UNINA
