Time-Dependent Material Link

The TDMatLink class links materials with their time-dependent properties (creep/shrinkage and compressive strength).

Class Attributes

TDMatLink.mats -> Dictionary of all material links.

Object Attributes

  • matID (int): The ID of the base material to which time-dependent properties are linked.
  • CnSName (str): The name of the CreepShrinkage definition to link.
  • CompName (str): The name of the CompStrength definition to link.

Methods

json

Returns a JSON representation of all Time-Dependent Material Links defined in python.

print(TDMatLink.json())
# Output:
# {'Assign': {'1': {'TDMT_NAME': 'CS_M25', 'TDME_NAME': 'Comp_M25'}, ...}}

create

Sends material links to Civil NX using a PUT request.

TDMatLink.create()

get

Fetches material links from Civil NX and returns the JSON representation.

print(TDMatLink.get())

sync

Retrieves Time-Dependent Material Link data from Civil NX and rebuilds the internal dictionary.

TDMatLink.sync()

delete

Deletes all material links from both Python and Civil NX.

TDMatLink.delete()

Examples

# Link materials with their time-dependent properties
link1 = TDMatLink(1, "CS_M25", "Comp_M25")  # Link material ID 1 with M25 properties
link2 = TDMatLink(2, "CS_C30", "Comp_C30")  # Link material ID 2 with C30 properties
link3 = TDMatLink(3, "CS_M25", "")          # Link material ID 3 with only creep/shrinkage

TDMatLink.create()

# Create IRC compressive CreepShrinkage properties

# Create IRC compressive strength properties

# Link materials with time-dependent properties

link1 = TDMatLink(1, "CS_M25", "Comp_M25")  # Link material 1 with M25 properties
link2 = TDMatLink(2, "CS_C30", "Comp_C30")  # Link material 2 with C30 properties

# Create all time-dependent properties in Civil NX
CreepShrinkage.create()
CompStrength.create()
TDMatLink.create()

print("All time-dependent properties and links created successfully!")

# You can also create them all at once using Material.create() if materials exist
# Material.create()  # This creates materials, creep/shrinkage, compressive strength, and links
