STRUCTURAL INTEGRITY ASSESSMENT OF A MINE HOST ROPE ATTACHMENT ELEMENT WITH A CRACK
Structural integrity assessment of an element (lifting plate) of a mine host rope attachment with a surface crack is performed using SINTAP/FITNET method. Different geometries of a semi-elliptical crack and load intensities are investigated. Material properties data used in the procedure are experimentally determined via tensile and fracture tests. Finite element method is implemented for determination of stress intensity factors and a stress profile necessary for the calculations. Two approaches to the assessment, FAD (failure assessment diagram) and CDF (crack driving force) provided in SINTAP/FITNET procedure are implemented and compared.
