AB  - In this paper, results of a long term experimental in-situ measurement of air
temperatures and heat fluxes trough a building wall surfaces, are presented. Indoor and
outdoor measurements were carried out simultaneously during the period of 1 month in
a dwelling of residential building located in Belgrade, Serbia. The data were used to
calculate the thermal transmittance of the wall according Standard ISO 9869-1:2014.
The U-value obtained from the experimental data and those calculated in steady-state
temperature regime are compared. Criteria for the data that have to be met in order to
get accurate U-value are discussed.

AB  - This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being regenerated by hard facing with subsequent cementation and quenching. The fatigue testing wider variable amplitude loading was used to determine the duration of operational life through measurement of wear. The obtained results demonstrated the impact of hard facing methods on gear endurance in operation. In the test on regenerated gears it was discovered that initial pits appeared almost simultaneously for different facing materials and a bit earlier than in tests on newly made ones, despite their considerably higher pitting rate. Apart from that, the tested operational lives of regenerated and newly-made gears were approximately equal and much longer than predicted.

AB  - U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. Eksperimentalni podaci dobijeni ispitivanjem pružaju značajnu osnovu za bolje razumevanje i objašnjenje fenomena zamora materijala. Niskociklični zamor (LCF) se javlja u procesu punjenja i pražnjenja reaktora, posuda pod pritiskom i cevovoda; proces zamora može ubrzati dodatni negativan efekat promene temperature i efekat agresivne sredine sadržane u posudi, kao i tokom perioda eksploatacije opreme u procesnoj industriji. U ovom radu prikazani su rezultati merenja J integrala pri niskocikličnom zamoru (LCF) metala šava niskolegiranog čelika povišene čvrstoće (HSLA), koji se koristi u proizvodnji posuda pod pritiskom postupkom zavarivanja pod praškom.
AB  - From a fracture mechanics point of view on welded joints, it is assumed that the welded joint is pre-cracked such as that the fatigue life of the pre-cracked structure is then determined by the period of crack growth under variable load. Experimental data obtained by testing provide a substantial basis for a better understanding and an explanation of the phenomenon of material fatigue. Low cycle fatigue (LCF) occurs during the process of charging and discharging of reactors, pressure vessels and pipelines; the fatigue can be accelerated by an additional negative effect of temperature variation and the aggressive effect of the media contained inside the vessel, and during the exploitation of the equipment in the processing industry. In the present paper the results are presented of J-integral measurements at LCF of a low-alloyed high strength steel (HSLA) weld metal used in the submerged arc welding process in the manufacture of pressure vessels.
