Level: Part, Part instance
Reference:
•
“Line spring elements for modeling part-through cracks in shells,” Section 26.10.1 of the
ABAQUS Analysis User’s Manual
Required parameter:
SIDE
Set SIDE=POSITIVE or SIDE=NEGATIVE to indicate which surface is cracked.
Optional parameter:
INPUT
Set this parameter equal to the name of the alternate input file containing the data lines for this

2. Crack depth at this location.
Repeat this data line as often as necessary to define the crack depth at all nodal locations along the
crack.
