Hello,I am modelling a tunnel longitudinally in Plaxis 2D. At the joints I would like to use node-to-node anchors to connect the top & bottom corners to model the gaskets. However the gasket has non-linear properties and therefore the stiffness increases with strain and the standard material models for anchors (or plates) are not appropriate. Is it possible to create a user-defined material for an anchor (or plate) and/or what other approaches would you suggest?
Dear Rebecca,
Unfortunately, it is not yet possible to define user-defined materials for structural elements. I will report this to our research and development team for future improvements to our program.
For now, it is only possible to use user-defined soil materials to simulate behaviour that goes beyond the constitutive models we offer in our native database.
It seems that it is still not yet possible to define user-defined materials for structural elements. When are we likely to get the option to define user-defined materials for structural elements?
Hello Ravi,
What exactly do you mean?
What are you missing from the current structural elements?Do you want to implement a material that applies to a different structural element, so for instance not for a plate, anchor, or embedded beam?
Note that PLAXIS allows the creation of User-Defined Soil Models as we already have soil elements in our finite element world. A material therefore will simply handle the stress-strain response of the soil element.
