Authoring: Stress Settings

Manage stress settings for a destructible instance.

Installation

To use this Node, you must enable source in the Extension Manager.

Inputs

Name	Type	Description	Default
execIn	execution	Input execution
Blast instance (prim)	bundle	Destructible instance to manage stress settings on. Connect to destructible output from another Blast node or output from an import USD prim data node.
Stress Gravity Enabled (stressGravityEnabled)	bool	Determines if gravity should be considered in stress calculations for this instance during sim.	True
Stress Rotation Enabled (stressRotationEnabled)	bool	Determines if rotation should be considered in stress calculations for this instance during sim.	True
Residual Force Multiplier (residualForceMultiplier)	float	Multiplies the forces added to bodies when bonds between them break.	1.0
Maximum Solver Iterations Per Frame (maxSolverIterationsPerFrame)	uint	Maximum number of solver iterations to perform per frame. Higher values will converge on stable stress solutions faster.	25
Compression Elastic Limit (compressionElasticLimit)	float	Limit for stress caused by being pushed together where bonds starts taking damage. Higher values make the material more resistant to damage. Unit: megapascal.	0.008
Compression Fatal Limit (compressionFatalLimit)	float	Limit for stress caused by being pushed together where bonds break instantly. Higher values make the material harder to break. Unit: megapascal.	0.01
Tension Elastic Limit (tensionElasticLimit)	float	Limit for stress caused by being pulled apart where bonds starts taking damage. Use a negative value to fall back on compression limit. Higher values make the material more resistant to damage. Unit: megapascal.	-1.0
Tension Fatal Limit (tensionFatalLimit)	float	Limit for stress caused by being pulled apart where bonds break instantly. Use a negative value to fall back on compression limit. Higher values make the material harder to break. Unit: megapascal.	-1.0
Shear Elastic Limit (shearElasticLimit)	float	Limit for linear stress perpendicular to bond directions where bonds starts taking damage. Use a negative value to fall back on compression limit. Higher values make the material more resistant to damage. Unit: megapascal.	-1.0
Shear Fatal Limit (shearFatalLimit)	float	Limit for linear stress perpendicular to bond directions where bonds break instantly. Use a negative value to fall back on compression limit. Higher values make the material harder to break. Unit: megapascal.	-1.0
