Bucket wheel excavators_Dynamic response as a criterion for validation of the total number of buckets
(Engineering Structures, 2020)
An original method for validation of the number of buckets on the working device of a bucket wheel excavator based on the dynamic response of its slewing superstructure (SS) is presented. A set of 16 seemingly acceptable ...
Influence of defects on limit loads and integrity of the pipeline at hydropower plant 'Pirot'
(Institut za ispitivanje materijala, Beograd, 2020)
Topic of this work is the integrity assessment of the pipeline section from hydropower plant Pirot. Crack-like defect size, maximum depth, is determined based on non-destructive evaluation - the largest crack depth is taken ...
