DCP3

Constant Strain Triangle With Crack Phase

• Number of Nodes: 3
• Number of DoFs: 3 (Translation, Translation, Damage)
• Zero Mass Entries On Damage DoFs

Reference

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.
