SHAKEDOWN OF BOLTS WITH A ONE-SIDED PROPAGATING CRACK

2002 Journal of Civil Engineering and Management  
Cyclic strains of joints may cause formation of a crack or cracks in a bolt thus changing its loading conditions. After crack appearance in a bolt it can be used if its length does not exceed a critical one. Modification of the shakedown theorem—the method of additional load—was applied in the investigation. The results—the analytical expressions of shakedown conditions are in a sufficiently good agreement with those achieved by other methods. Differences occur due to failure to get an accurate
