After several decades of development we are happy to announce that the Tochnog Professional finite element program has become free. Both for academic and commercial use. We are extremely grateful […]
Hello, I am using clay hypoplastic umat code and trying to verify the code with the simulation on the paper of Prof. Masin. I found in the paper (Masin, 2005, […]
Hello all, I am currently working on the FE modeling of anchors installation into the soil using the CEL analysis in Abaqus. I tried to use the hypoplastic vumat for […]
I have been a =n user of the open source version of Tochnog for since 2004. I have been one of the maintainers and have contributed to the capabilities of […]
The Tochnog Professional finite element program is now available as free version with 100 elements. It can be downloaded without registration from http://www.tochnogprofessional.nl. Several commercial and free pre- and postprocessors […]
Dear Prof David / SOil model community, I am performing coupled consolidation analysis for deep excavation in clay using HP clay model in Plaxis 3D. Performing the undrained analysis, the […]
Use total plastic strain and Cauchy for 3D
strain=sqrt(0.5*(pe11-pem)^2+0.5*(pe22-pem)^2+0.5*(pe33-pem)^2+pe12^2+pe23^2+pe13^2)
pem=(pe11+pe22+pe33)/3
for explixit pe23=array(5) and pe13=array(6)
for implicit pe23=array(6!) and pe13=array(5!)*
for plainstrain: pe13 and pe23 do not exist
*
for explicit vgetvrm gives you e12,e23,e13
for implicit you maybe get y12,y13,y23: you have to check this
