Prediction of the load carrying capacity of elevated steel fibre reinforced concrete slabs [PDF]
, 2017 A novel methodology is developed for predicting the load carrying capacity of elevated steel fibre reinforced concrete (E-SFRC) slab systems. In the proposed approach the depth of slab’s cross section is discretized into several layers, and the number ...

Research of boride layers growth kinetics on C45 carbon steel
Metalurgija, 2012 This study reports an evaluation of borides formed on C45 steel. Pack boronizing has been carried out in temperature range 870 – 970 °C with durations 4 – 8 h. Average thickness of boride layers ranges from 60, 6 to 181, 2 µm. Through application of basic laws of diffusion, values of frequency factor and activation energy have been determined and ...

Thermal Response of C45 Steel in High and Very High Cycle Fatigue
Procedia Engineering, 2015 AbstractHigh and very high cycle fatigue regimes are rapidly reached using an ultrasonic fatigue machine working at 20kHz. For instance, a fatigue test up to 109 cycles lasts 14hours at 20kHz while it lasts 100 days at 100Hz. The heating of specimen can reach several tens of degrees at 20kHz fatigue tests.
