DETERMINATION OF MECHANICAL PROPERTIES OF COMPOSITE MATERIALS-THE RUBBER CONVEYOR BELT WITH CARTRIDGES MADE OF POLYESTER AND POLYAMIDE
A large number of cracking the conveyor belt, which occurs during exploitation at stress level lower than the permitted, indicates a risk of damage and breakage. Therefore in designing it isExpand
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
Abstract The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIOMOL 490 K, weldedExpand

Effect of Microalloyed Steel Welding Procedure on Fatigue Crack Growth
The application of high strength steel, e.g. NIOMOL 490K, developed for highly loaded welded structures and low temperatures, depends on properties of welded joint critical regions. Strength,Expand
THE EFFECT OF FIBRE ORIENTATION ON FRACTURE PROPERTIES OF GLASS FIBRE- EPOXY COMPOSITE UTICAJ ORIJENTACIJE VLAKNA NA KARAKTERISTIKE LOMA KOMPOZITA TIPA
The effect of glass fibre orientation in an epoxy matrix composite on impact load and fracture toughness is experimentally analysed by testing Charpy V notched specimens, and notched CT specimens.Expand
Treatment Analysis of Welding Structure in the Presence of a Crack Type Defects
The largest number of welded structures in operating conditions is exposed to variable loads, which is why the share of fatigue fracture in the failure of welded structures is higher than others. TheExpand
EFFECT OF VIBRATION ON THE VARIATION OF RESIDUAL STRESSES AND IMPACT ENERGY IN BUTT-WELDED JOINTS
The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An importantExpand
