How to set up composite failure criteria and results

Erik Kostson

Using mechanical scripting, how can we define composite failure criteria and composite failure results (using Composite Failure Tool inside mechanical)?

Erik Kostson

Below is an example (max strain failure):

# Create a new Composite Failure Criteria object
composite_failure_criteria = Model.AddCompositeFailureCriteria()

# Activate the Max Strain Failure Criterion
composite_failure_criteria.MaximumStrain.Active = True
#composite_failure_criteria.Puck.Active = True # for Puck fai.

# Modify the Max Strain Failure Criterion settings
composite_failure_criteria.MaximumStrain.EvaluateMaterialThreeDirectionFailure = True
composite_failure_criteria.MaximumStrain.MaterialOneDirectionFailureWeightingFactor = 1.5
composite_failure_criteria.MaximumStrain.TensileLimitMaterialOneDirection = 0.01
#composite_failure_criteria.Puck.MatrixTensionFailureWeightingFactor = 1.2 # for Puck

solution = Model.Analyses[0].Solution
composite_failure_tool = solution.AddCompositeFailureTool()

composite_failure_tool.Properties[3].InternalValue=2
composite_failure_tool.Properties[4].InternalValue=composite_failure_criteria.ObjectId

composite_failure_result = composite_failure_tool.AddInverseReserveFactor()
