Under Development

The new remeshing capability in Zencrack 9.0-1 was an initial implementation onto which more capability has been added with the latest releases, 9.3-1 and 9.4-1, having the ability to cater for multiple remeshing cracks and merging of remeshed regions respectively.

The multi-crack remeshing capability in 9.3-1 included a limitation that the remeshing regions of the cracks do not touch or overlap. Removing this limitation was the main development activity for version 9.4-1 and a pre-cursor to further generalising the remeshing capability for multiple cracks in subsequent releases. An example is shown below, from version 9.4-1, in which two cracks whose remesh regions are initially separate become embedded in a single remesh region after some growth has taken place.

A non-linear Kujawski-Ellyin crack growth law will be implemented as per the publication:
