For various viscoelastic models which are composed of springs and dashpots,their creep/rdaxation functions usually are the sum of a series of exponential functions. By virtue of this characteristic, the recursion formulae to calculate viscous strain/stress increments during a time step can be founded. Moreover,the corresponding FEM formulae are also given. A simple example in the end of this paper demonstrates that the precision of computational results is much improved with the method.
