Hi ABAQUS users:
I am trying to compare the results of my fracture mechanics analysis with
that of Example 7.2.2 in the ABAQUS worked Examples. I would like to make
the same model but I can't get the node location from the run stream shown.
Apparently they just input the length of the edge and number of elemenst and
use the command
NFILL=SING to generate crack elemenst that are "a square of the distance
from the crack tip in lenght". From the way I understand this is that they
get elemnst that are gradually larger away from the crack tip. What I am
trying to figure is the progression function they use to get the length of
each element. When I do it by hand I have great difficulty trying to get
one function that works for lengths > 1. and those < 1.
Any help would most appreciated.
Thanx
Nirmal
