Hyperviscoelasticity

We provide a general framework to build hyperviscoelastic behaviour. This framework is described here.

Viscoelasticity

• GeneralizedMaxwell
• This page describes how to implement the Skorohold-Olevsky Viscous Sintering (SOVS) model.
• This page describes how to implement Torelli’ behaviour describing the load induced thermal strain in concrete.
• This page describes the implementation of the ̀Burger_EDF_CIWAP_2021 which aims at modelling the following phenomena in concrete:
  • Elasticity
  • Drying shrinkage
  • Basic creep
  • Drying creep

Non linear elasticity

• A non linear elastic behaviour that mimics the Ramberg-Osgood plastic behaviour on monotonic loadings (usefull in fracture analysis
