Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels
steel research international, EarlyView.The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

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 ...

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation
European Journal of Oral Sciences, EarlyView.Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

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

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3404-3419, August 2026.ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...
