ULTRASOUND IN RELIABILITY
Reality in industry, thinking of maintenence approach in many cases, is disproportional with available technologies and knowledge. This situation is decreasing company´s competitiveness or decreasing the possible or projected profit. In the global market, when resources show stable or increasing prices, and final product price drop, future is...

ASSET MANAGEMENT IS MORE THEN JUST ASSET CARE (MAINTENANCE): EDUCATION, CULTURE CHANGE AND COLLABORATION IN ASSET LIFE CYCLE MANAGEMENT
This paper summarizes the experiences of many organizations in migrating from an asset care (maintenance) culture to a whole life cycle asset management approach, and the benefits obtained from this transformation. It will explain the evolution of the modern discipline, and the practical steps that can be taken to break down the barriers between de...

FRACTURE MODE-MIXITY IN SYMETRICAL BEAM SPECIMENS: FPZ LENGTH INFLUENCE
Mixed-mode fracture in delamination test utilizing double cantilever specimens loaded with bending moments is investigated in the paper. FEM simulations are performed using cohesive zone model where different configurations of test loadings and two critical fracture energy values, ie. two fracture process zone lengths, are considered. Fracture ener...

MIRCE PROFITABILITY EQUATION
Commonly, maintenance is perceived as “fixing broken things”. As such, it is associated with failure consequences and unplanned expenses, both of which negatively impact business plans or customer satisfaction. However, as failures are an inevitability of the life of any technological system, it would be worthwhile to start looking at m...

ROBOT FORCE CONTROL METHODS
Robot manipulators are usually used in many industrial apllications where a number of practical tasks should be executed. The very important part of that execution is interaction between robot and environment. Control of the interaction is crucial for successful execution of industrial processes. Typical applications include deburring, machining, a...

TESTING OF NEW TYPE OF SPLIT SLEEVE FOR PIPELINE REPAIRS BY INTERNAL PRESSURE
Repairing technologies for pipelines still require attention due to large extent of distribution network containing different construction parts including elbows, branch connections and others. Repairing of the defects in the branch connection area without interruption of the gas supply is very difficult. Such defects mostly require replacing of th...

MIX DESIGN OF SELF-COMPACTING CONCRETE CONTAINING HIGH VOLUME CALCAREOUS FLY ASH FOR PRECAST ELEMENTS
In this paper, the possibility of proportioning self-compacting concrete with high volume calcareous fly ash (W) for precast elements has been investigated. So far, numerous mix design methods for self-compacting concrete have been developed, so as the most appropriate method in this investigation, the UCL method was chosen. In the first phase, the...
