Title:Analysis of crack initiation and growth in pinned joint of crane counterweight bar
Abstract:The paper deals with the research on the crack growth in a bolt connection of a lug for crane counter weight bars. Counter weight bars are structural elements subjected to very heavy loads and therefore need special attention. The main purpose of this research is to determine the number of load cycles required for a crack to propagate from initial to criticakl crack length, whenthe final failure can be expected to occur. All required material parameters and experimental results were determined in our previous research. The influence of the initial crack siye upon the remaining life of the lug is reserched numericallu by means of FE analysis and analytically by use of the corrected analystical model.
Keywords:fracture mechanics, cyclic loading, fatigue crack growth, service life prediction, numerical analysis, bolt connection
