displayed each time the plot view containing the crk item plot item is regenerated.A fully-
captioned view(“view of cracks”),can be generated by setting the parameters described above and
calling crk makeview.If new cracks form,they will be displayed in this view but the caption
information will no longer be accurate.To update the view,simply call crk makeview again.
Figures 3.64 and 3.65 provide an example of the use of the crk item plot item with crk icon
=0,crk iconmult=1.0,and crk ctype=0.These figures were generated from the file
“Agc 00-bw1.SAV.”Figure 3.64 illustrates how a microcrack is present at the location of each
broken bond between two particles.In this figure,both colors for the crk item plot item have
been set to black.Figure 3.65 provides a clearer illustration of the material microstructure.In
this figure,the colors for the crk item plot item have been set to yellow and black,with yellow
indicating contact-bond normal failure,and black indicating contact-bond shear failure.
