Abnormality in the Theory of Necessary Optimality Conditions
The problems of existence, non-uniqueness, abnormality of solutions arising from the using of necessary optimality conditions are discussed in terms of the extension principle and sufficient optimality conditions. Simple examples are used.

Lagrange multipliers in linear elastostatics
The thesis deals with the use of Lagrange multipliers, explaining the principle of their use and the calculating process. Lagrange multipliers are introduced into joints of a given truss structure. The calculation is conducted using minimalization of the

The Hamilton-Jacobi Treatment of Complex Fields as Constrained Systems [PDF]
The complex scalar field is treated as a constrained system using the Hamilton-Jacobi approach. The reduced phase space Hamiltonian density is obtained without introducing Lagrange multipliers and without any additional gauge fixing condition.

Bounds for lagrange multipliers and optimal points
We describe two methods for use in constrained optimization problems. One method computes guaranteed bounds on both the Lagrange multipliers and on the location of the optimal points. The other method bounds the Lagrange multipliers only.

Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Lagrange multipliers in incentive-constrained problems
Some recent work on dynamic incentive constraints poses the question of existence and regularity of Lagrange multipliers in optimization problems in infinite dimension with infinitely many-side constraints, which may not be concave. We provide sufficient

Significance of Lagrange multipliers in cross-section adjustment [PDF]
A natural derivation of the explicit prescriptions incorporated in least-squares adjustment codes is given. The central role of the Lagrange multpliers in this conditional-minimum problem is noted.

Sensitivity analysis is an integral step in the interpretation of the solutions of optimization models, particularly when there are uncertainties in the numerical values of model parameters. Conventional approaches to sensitivity analysis rely on the use

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
