You can try stabilizing using contact control make sure the static dissipation energy is roughly less than 5% of the total internal energy during the simulation to ensure accuracy is not significantly affected. The viscous energy is the energy dissipated by damping mechanisms, including bulk viscosity damping and material damping. How to obtain the energy dissipation output when using abaqus cohesive surfaces. Using the commercial fe software package abaqus, this was achieved using a single layer of quadrilateral shell elements. This is a basic introduction for structural fem modelling using the popular software abaqus. A fundamental variable in the global energy balance, viscous energy is not part of the energy dissipated through viscoelasticity or inelastic processes. Learn more about the simulia abaqus software and how to use it with these abaqus simulation tutorials. In this video the basics are covered including creating. The damage model uses the hashin criteria to capture the. Abaqus analysis methods on highly restrained pipeline with. Abaqus tutorial fluid structure interaction using co. Within the step definition, automatic stabilization can be chosen, e. If the default value for the dissipated energy fraction is used, the adaptive automatic stabilization scheme discussed in the next section will be activated automatically by default in the step.
