Fig. 14.2 PE1 of the central point’s j = 67 versus time
Fig. 14.3 X Evolution of the point j = 67 versus time
Consider now an ASTM specimen, for tensile test (see Fig. 14.8) during fracture.
We are using a rectangular centred lattice with neighbour numbers reduced to five,
to increase point’s mobility. Distance fracture, df , is 11 units, and the speed was
0.6 step/unit time. The fracture occurs close to the top of the profile and not in the
central area. Studies, still in progress, show how the fracture zone can be influenced by
varying working conditions. We can render the fracture more or less brittle changing
the model parameters, like neighbours’ number, type of lattice, speed, etc. The PE1
plot in this case is less significant because it does not take into account the fictitious
points; we are working on it to make this parameter meaningful also in fracture case.
