Impact toughness and fracture toughness
Witryna31 lip 2011 · Abstract: The fracture toughness and strength of materials are adversely affected by the cracks in the materials, which can be induced during manufacturing, assembly, and usage. In this study, the effect of crack length and crack location on the fracture toughness of woven glass and carbon reinforced hybrid and non-hybrid … Witryna1 cze 2024 · The influence of temperature on impact and fracture toughness values in different regions of a welded joint is analysed for low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. Standard Charpy specimens were tested on instrumented pendulum to separate total impact energy into energy for initiation and …

WitrynaThis paper investigates effect of thermal aging on reduction of fracture toughness of CF8 M cast stainless steel. To predict fracture toughness of un-aged and aged materials by numerical analyses, finite element damage analysis is used in conjunction with strain-based fracture model. Witryna15 cze 2024 · To investigate the role of fracture toughness on impact-abrasion, a simple experiment was designed in which the hot-rolled steel was reaustenitised at 900 °C for 1 h and quenched so that the scale of the microstructure increases and the toughness decreases. The resulting microstructure is shown in Fig. 2.
Witryna7 kwi 2004 · THe fracture toughness at instability, J C, was also computed and plotted against the amount of stable crack growth in order to construct J-R curves as a function of size and strain rate. From these curves an alternative critical fracture parameter, K JIC, was calculated. Weibull statistics were used as a tentative approach for treating … WitrynaObjectives: This paper presents the effect of silane treatment of S-2 Glass fibres on the fracture toughness and water sorption/solubility behaviour of fibre-reinforced …
