Journal ArticleA Dual Variational Principle for Nonlinear Dislocation DynamicsAcharya, Amit<title>Abstract</title> <p>A dual variational principle is defined for the nonlinear system of PDE describing the dynamics of dislocations in elastic solids. The dual variational principle accounting for a specified set of initial and boundary conditions for a general class of PDE is also developed.</p>Springer2023-03-0910467916Journal of Elasticity0374-3535https://doi.org/10.1007/s10659-023-09998-52021019National Science Foundation
