The aim of the present paper is to propose a special kind of finite element procedure for dynamic and static analysis of civil engineering structures (e.g. trusses, beams, shells and spatial structures) including elasto-viscoplastic models. The Chaboche model with damage has been chosen from the wide range of available elasto-viscoplastic constitutive models for numerical calculations. The main advantage of the presented approach is the possibility of interference in subroutines and adjusting them to a particular problem (e.g. altering the form of constitutive equations). A user-defined UVSCPL subroutine has been proposed to introduce the elasto-viscoplastic model into the MSC.Marc system.
