DCP3
Constant Strain Triangle With Crack Phase
Number of Nodes: 3
Number of DoFs: 3 (Translation, Translation, Damage)
Integration Scheme: Single Point Centre
Zero Mass Entries On Damage DoFs
References
There are a lot of papers on the phase-field model. A staggered scheme with maximum strain energy is adopted as an illustration of implementation.
Syntax
element DCP3 (1) (2...4) (5) (6) (7) [8]
# (1) int, unique element tag
# (2...4) int, node i, j, k
# (5) int, material tag
# (6) double, characteristic length
# (7) double, energy release rate
# [8] double, element thickness, default: 1.0
Remarks
The third DoF is the damage variable. Boundary conditions can be assigned.
The characteristic length
(7)
can be set to zero to automatically determine the value based on geometry.
Recording
This model supports the following additional history variables to be recorded.
