Strain compution in Triaxialstresscontroller
These days I'm a little puzzled with the strain compution in TriaxialstressController.cpp ,just as follows:
strain = Mathr::Log(width0/width);//Eq(1)
strain = Mathr::Log(height0/height);//Eq(2)
strain = Mathr::Log(depth0/depth);//Eq(3)
IIRC,Log means not log10 but ln as usual .Is it right?
Eq(1 to 3) is different from the common compution of strain like:
and, in PFC3D manuals(V3.0)->users' guide->problem solving with pfc3d Page 47, I found another Eq for strain compution:
Are the 3 methods all right? They're designed for different fields?
Thanks for any suggestion.
