SANISAND dllEmilio Bilotta||Finite Elements|2 |
Hi there, I’ve used successfully used SANISAND .dll with Plaxis 2016, but after switching to 2017 and now 2018 the .dll seems not to work (the parameter fields appear without […]
Automatic calibration software ExCalibre has been launchedDavid Mašín||Constitutive Modelling|0 |
On behalf of the team of developers I am happy to announce that, after more than four years of development and testing, ExCalibre has just been launched. ExCalibre is a […]
A PhD-level course on hypoplastic constitutive modelling intended for both academia and practitioners.
Multilaminate model (Schädlich, Schweiger and coworkers) is now available for download as Plaxis UsrMod. Thanks to Helmut Schweiger and coworkers from Graz University of Technology, Institute of Soil Mechanics, Foundation Engineering and Computational […]
Multilaminate constitutive models are based on the concept that the material behaviour can be formulated on a number of so-called integration planes with varying orientation. In addition to other features, the model predicts anisotropic soil stiffness at small strains.
Package contains Plaxis UDSM (dll files only), package documentation in pdf and related journal publication and PhD thesis pdf files. Authors are researchers from the Graz University of Technology.
Error: permission to access files denied (Hypoplasticity in PLAXIS)Katharina Fechtner||Constitutive Modelling|7 |
Hello, I am trying to implement the dll for hypoplasticity in Plaxis 3D. It runs through both the Initial Phase and a Nil Step. However, when it calculates about 20 […]
