In Vitro Mechanical Tests for Modern Dental Ceramics
Frontiers in Dentistry, 2006 The fracture resistance of all-ceramic restorations is one of the major concerns in clinical applications of these materials. Before initiating a time-consuming and costly clinical investigation, an in vitro study can help to estimate the in vivo ...

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

Biography of Are Tsirk (1937-2015): Flintknapper and scholar
Journal of Lithic Studies, 2015 Are Tsirk was as much a scholar as he was a flintknapper. These disciplines were intertwined and expressed in his experimental research, by way of his exploration of fractography, and his replication of stone tools which spanned the archaeological record

Experimental Study on the Fatigue Behavior of Ti‐6Al‐4 V Bolted Joints Containing Burrs
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT One‐way assembly accelerates aerospace manufacturing operations but risks leaving drilling burrs within mechanical joints. The detrimental impact of burrs on fatigue strength is widely recognized in the literature, but the mechanisms driving this “knock‐down” remain unclear. This investigation focused on mechanically fastened Ti‐6Al‐4 V single‐
