Abstract
The main purpose of this study is to have an overview of critical crack
size and growth, and their influence on the remaining fatigue life of
door corner and associated bulkhead in order to set proper period for
repair and service of structural components. Growth of cracks is
calculated by using the fracture mechanics for two cases: the first
assessment is made for a passenger ship's door corner where no visible
cracks have been detected and the second assessment is conducted for the
structure where cracks have been detected during inspections. The
analysed door corner is situated in area of maximum shear forces of the
ship hull. Loading of the door corner is generated by applying the
measured nominal shear stresses of the associated bulkhead. Measured
stresses correspond to 1500-hr data of a passenger ship's normal
operation in different wave conditions.
