Hi everyone, i want to carry out some transient dynamic analysis. as far as I know, dynamic steps in abaqus does not allow for pore pressure build-up and dissipation, and […]
I tried to model sample of triaxial test in Abaqus program. I used hypoplastic subroutine. The parameters used in hypoplastic model was Hochstetten sand the given in website “https://web.natur.cuni.cz/uhigug/masin/plaxumat/node5.html”. The […]
Hello.. I am testing SaniSand constitutive model as published by Mr. Masin at this site. The Abaqus is V21 and the visual studio 2017 with OneAPI compiler, the Abaqus verification […]
Hello everybody, Using Hypoplastic model for clays, with intergranular concept parameters, I am simulating a simple oedometer test, phase by phase, using a dummy layer on the top of the […]
Hello everyone; I have implemented the Sanisand constitutive model (UMAT) in abaqus in the scope of performing a dynamic analysis on a 3D soil-pile interaction problem. I have succeded in […]
DIANA 10.5 was released in 2021. It features many powerful capabilities to model soil-structure interection. See more in https://dianafea.com/2021-DIANA10-5-Release
Dear all, I’m looking for a sigini and sdvini subroutine examples to calculate soil initial state with rest coeficient K0 method or ICP-05 method or any method available. thank you. […]
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
