Abstract:
The use of fracture mechanics techniques in the assessment of
performance and reliability of structures is on the increase and the
prediction of crack propagation of an existing or postulated flaw in a
structure plays an important part. A software simulation tool, which
uses FEA, has been developed to quantitatively predict the propagation
of 3D non-planar cracks through structures. This tool allows calculation
of stress intensity factors and energy release rates and can be applied
in a variety of commercially important applications. These include
design of laboratory experiments, testing and developing advanced
materials, assessing the effects of surface treatments and the study of
component repairs.
