Download Package of Matlab Driver
Simple Matlab element test driver running elasto-plastic and hypoplastic models.
Programmed in 2012 by Claudio Tamagnini and David Mašín for the ALERT Olek Zienkiewicz Course "Constitutive Modelling", which took place at Technische Universität Dresden, Germany, 17-21 September 2012.
Associated Software and Constitutive Models
Clay hypoplasticity is an advanced incrementally non-linear constitutive model based on critical state soil mechanics developed specifically for simulation of fine-grained materials.
Sand hypoplastic model is an advanced incrementally non-linear constitutive model for sand, an outcome of an extensive research at Karlsruhe University in 1990's.
Simple Matlab driver running elasto-plastic and hypoplastic models. Rather an education tool than a serious calibration software, but some may find it useful to familiarize with the structure of constitutive model equations and to run simple element test simulations.
Thanks for this. It would be very educational for me, I think.
Happy that it will be useful!
Thanks for this.
Hello David sir,
i am trying to code the sanisand model in triaxial space in Matlab but couldn`t succeed yet. can you provide Matlab code or reference to help the same. I shall remain thankful
Regards
SAQIB
Thanks for sharing this, it’s helpful for me!
Professor Masin,
Thanks for sharing the code.
I have a question concerning how to specify stress path, for instance compression drained, say for “hypo_sand” model?
I found in update.m there is a matrix named “path_info”, but cannot find further information on this.
Thank you for your time.
Hi Xiang, this is defined in input_data.m, using “icode” variable. Explanation of codes is in comments. drained triaxial compression has icode=4. David
Dear Prof.Mašín,
Thanks for your explanations and directions in this forum.
I solicit you to send me the hypo version for unsaturated soils for Plaxis.
Thank you for your time.
