【Abstract】 This paper presents a virtual work equation with viscoelastic boundary conditions, which is used to consider the nonlinearity of dynamic contact conditions. The FEPG system is expanded by adding a FEPG script code for solution of the equation and its boundary conditions, and a new code is obtained. This code is validated by a test case.

【Key words】 structural dynamics; viscoelastic boundary; FEPG; dynamic contact; virtual work equation
