Scaled boundary finite-element shakedown approach for the safety assessment of cracked elastoplastic structures under cyclic loading

Many structures in Australia have passed or are approaching their design life. One of the most common happening in an ageing structure is the appearance of cracks. The safety of a cracked structure is a major concern to general public and government authority if no reliable safety evaluation can be performed. In this research project, an advanced numerical tool will be developed to predict the stability of cracks and thus the safety of a cracked structure. Such a tool, which does not yet exist, will help engineers and government authorities in deciding on the necessity and type of rehabilitation, retirement or replacement of a cracked structure.
