Abstract
This paper presents a symmetric, double integration boundary integral equation (BIE) approach to linear viscoelastic analysis. The time evolution of the boundary unknowns is shown to be characterized by a variational theorem over an arbitrary time interval and by a min-max theorem from the time origin to infinite (minimum for displacements, maximum for tractions). Boundary element (BE) discretization in space and time leads to algebraic equations with symmetric coefficient matrix.
