Abstract
ACR-program (Automatic Finite Element Model Generation
for Part Through Cracks) has been developed at the
Technical Research Centre of Finland (VTT) for automatic
finite element model generation for surface flaws using
three dimensional solid elements. Circumferential or
axial cracks can be generated on the inner or outer
surface of a cylindrical or toroidal geometry. Several
crack forms are available including the standard
semi-elliptical surface crack.
The program can be used in the development of automated
systems for fracture mechanical analyses of structures.
The tests for the accuracy of the FE-mesh have been
started with two-dimensional models. The results indicate
that the accuracy of the standard mesh is sufficient for
practical analyses. Refinement of the standard mesh is
needed in analyses with high load levels well over the
Iimit load of the structure.
