Computation Method in Failure Analysis of Mechanically Fastened Joints at Layered Composites
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
This paper considers a computation method in failure analysis of layered composites containing pin-loaded holes. The investigation is focused on developing a reliable computation procedure to analyze initial failure load ...
Uncertainty evaluation of the conducted emission measurements
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
For the evaluation of measurement uncertainty in measuring the conduction emission, in this paper we propose a new model which uses mixed distribution. Evaluation of probability density function for the measurand has been ...
Cold weld cracking susceptibility of high strength low alloyed (hsla) steel nionikral 70
(Faculty of Metallurgy, 2014)
