LocalConstraints2¶

Source: userfiles/TwoBarTruss/subsystem2/LocalConstraints2.py

Local constraints module for Two-Bar Truss subsystem 2.

Defines the buckling stability constraint for bar 2 (compression member) in the Two-Bar Truss problem.

Classes¶

LocalConstraints2¶

Inherits from: LocalConstraintsInterface

Local constraints class for Two-Bar Truss subsystem 2.

Evaluates the Euler buckling stability constraint for bar 2.

Attributes:

None specific to this class; inherits from LocalConstraintsInterface.

Methods¶

init(self) → None

Initialize LocalConstraints2 instance.

evaluateEqualityLocalConstraints(self, subsystem: LocalSubSystemBasis) → None

Evaluate equality constraints for subsystem 2.

Args:

subsystem: The local subsystem basis containing state information.

evaluate_Jacobian_EqualityLocalConstraints(self, subsystem: LocalSubSystemBasis) → None

Evaluate the Jacobian of the local equality constraints.

Args:

subsystem: The local subsystem basis containing state information.

evaluate_Hessians_EqualityLocalConstraints(self, subsystem: LocalSubSystemBasis) → None

Evaluate the Hessians of the local equality constraints.

Args:

subsystem: The local subsystem basis containing state information.

evaluateInEqualityLocalConstraints(self, subsystem: LocalSubSystemBasis) → None

Evaluate inequality constraints for subsystem 2.

Computes the buckling constraint (sigma2 / sigma_Euler)**2 - 1 <= 0, magnitude-compressed via a sign/zero-crossing preserving power map so the feasible set is unchanged (see power_ratio below).

Args:

subsystem: The local subsystem basis containing state information.

evaluate_Jacobian_InEqualityLocalConstraints(self, subsystem: LocalSubSystemBasis) → None

Evaluate the Jacobian of the local inequality constraints.

Args:

subsystem: The local subsystem basis containing state information.

evaluate_Hessians_InEqualityLocalConstraints(self, subsystem: LocalSubSystemBasis) → None

Evaluate the Hessians of the local inequality constraints.

Args:

subsystem: The local subsystem basis containing state information.
