Need the references of penetration into soil target

Submitted by huang peng on

   I want to simulate the penetration into soil target, but I don't find the satisfied references about this simulation.The penetration into soil target will be simulated by the finite element method or meshless methods in my project. I think the good experimental results can verify the simulation.

   Can you give me some references of  penetration into soil target?

   Thank you for your help.

   

Problem of contact data in ABAQUS 6.8 version

Submitted by jin haeng Lee on

Hi.

I have an issue related to recent change in ABAQUS new version.

 I've recently found a problem related to cotact data in ABAQUS new version, 6.8. I use fil files, but I've heard from a Simulia engineer that data file also has the same problem (I have not checked it out yet.)

Dear All,



Could you suggest any literature or online step by step tutorial on how to create your own subroutines in ABAQUS like umeshmotion or umat. Any relevant information would be much appreciated. I am looking for information that are not covered in the ABAQUS manual.



Thanks very much in advace,



Nicholas


Question about curve fitting indentation data with large residual strain

Submitted by Yao Jiang on

I am trying to use finite element modeling of indentation experiments
to extract hyperelastic material parameters. I am having a dilemma,
when the tissue has residual strain, the model couldn't achieve the
high nonlinear relationship between displacement vs reaction force as
measured in the experiments.



I have tried several strain energy potentials,

1) W=A/B*{exp[B(I1-3)]-1}

2) W=C10(I1-3)+C01(I2-3) 

3) W=C10(I1-3)+C20(I1-3)^2+C30(I1-3)^3

4) Arruda-Boyce type model

Weld analysis using ansys

Submitted by sudheesh on

Inorder to find out the residual stresses and distortions in butt weld due to thermal loads in steel plates, i have used

shell57 for thermal and shell43 for structural.The material properties used are temperature dependent.



I  carried this out in two steps.







The thermal analysis is carried out first.

A moving heat source is used to generate the temperature distribution on the plate.
