Extremely Curved Cracks

Submitted by Ettore Barbieri on

 

The word "extreme" seems to be "trending" a lot these days, see the recent discussions on the new journal Extreme Mechanics Letters.

My collaborator Ruben Sevilla at Swansea and I were interested in very curved crack paths that develop in nature and have been replicated experimentally in thin films attached to elastic substrates.

I have few general queries regarding MLPG meshfree method

1. Can the trial and test functions be taken same for solving a problem

2. In the problem if there are zones with different properties, for example different Coeffiencient of Permeability in the aquifers (Plan view-wise), how to handle the interface between the zones and assemble the global matrix
