Analysis and Optimization of Nonsmooth Arches

SIAM Journal on Control and Optimization, 2002
The Kirchoff-Love model for a smooth clamped arch is considered first. A new treatment for that classical model is developed. A variational formulation, based on optimal control theory, is introduced and, using duality-type arguments, the deformation of the arches are explicitly expressed by integral formulas.

Nonsmooth analysis of eigenvalues

Mathematical Programming, 1999
Subdifferentials (limiting Fréchet, Clarke) of the composition \(f\circ \lambda \) of extended real valued permutation invariant functions \(f\) and the eigenvalue vector function \(\lambda \) of a symmetric matrix \(X\) are calculated using the transformation to principles axes.

Elements of Nonsmooth Analysis

2003
In this Chapter we recall important definitions and results from the theory of generalized gradient for locally Lipschitz functionals due to Clarke [8], different nonsmooth versions of Palais-Smale conditions and basic elements of nonsmooth calculus developed by Degiovanni [9], [10].
