DCP4

Bilinear Quadrilateral With Crack Phase

• Number of Nodes: 4
• Number of DoFs: 3 (Translation, Translation, Damage)
• Integration Scheme: 2^nd Order Gauss
• Zero Mass Entries On Damage DoFs

Syntax

element DCP4 (1) (2...5) (6) (7) (8) [9]
# (1) int, unique element tag
# (2...5) int, node i, j, k, l
# (6) int, material tag
# (7) double, characteristic length
# (8) double, energy release rate
# [9] 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.
