Periodic boundary conditions are routinely employed in molecular dynamics simulations to simulate bulk material and remove surface effects. However, the effect of periodic boundary conditions on simulation results is not well understood. In this paper three distinct approaches are explored in an eff

The problem of structures' sensitivities to uncertain boundary conditions is presented in this paper and the eect of uncertain prescribed displacements on the static response of structures is discussed. The imprecise or uncertain prescribed displacements are treated as fuzzy quantities with known me

In this paper, a convenient strategy is developed to "nd solutions for a class of uncertain-boundary-value problems by the Boundary Element Method (BEM). Such problems are ill-posed, but ill-conditioning of the associated algebraic systems of equations can be controlled to a large extent, and useful
