Micro Abstract:
In this contribution tensile experiments with constant load over time and with cyclically removed load are presented. The dog bone specimens out of polyoxymethylene show time dependent reversible as well as irreversible deformations followed by breakage. To reproduce this, a viscoelastic-viscoplastic constitutive model with damage and recovery is applied. Since the occurring deformations are large, an approximative large strain formulation is used still allowing an additive strain split.
