Problems with gravity loads

Hello to all,

 I`m carring out a simulation with abaqus of an underground storage tank. I modelled the tank using shell elements (conventional) and for the soil I used solid element. I want the stress on the top of the tank caused by the efect of the soil that is on the top.

The applied load is Gravity in the y-direction (-10 m/s2) to the whole model and I`m using abaqus/standard. I defined the contact between the tank and the soil.

The problem is that the job end saying "too many attemps for this increment". I used different increments but all of them with the same result.

What can I do or what am I missing ?

 

Thanks to all!

I am doing research involving the finite element modeling of a human head namely Scalp, Skull, Brain & Duramater using Abaqus/CAE. I have finished modeling the parts, assigning the material properties, assembling and meshing the said model. I need to drop the whole assembly onto a 'floor'. What step should I choose. Also what interaction would I have to create so that the head would shear when it is dropped a distance less than 1 cm. Also bear in mind that it should not bounce.

 Thank you.

Modeling contact in ABAqus

i am working on modeling hertzian contact (general and standard conact in abaqus). i want to know how to model contact between surfaces of my assembly.  i modeled it but it gives me error saying that my regions in the model are not connected.

How should I go about? is contact modeling different than just constraining the surfaces ?

Constitutive model

woven fabric

Dear all,

 

I'm a researcher in the area of applied mechanics. Currently, I'm surveying articles on the constitutive and numerical modeling of fiber reinforced polymer composite. In particular, the fiber is a glass woven fabric. The matrix is the epoxy (thermoset which shrinkages when curing is completed). I want to know woks relevant to this kind of materials. I have found some "compressible hyperelastic model" which is for the epoxy only. Any comments or suggestions will be welcomed!

 

Best regards,

Coupled Euler-Lagrangian FEA to simulate fluid entering micro pores in Abaqus/Explicit

Submitted by priyadd84 on

Hi all,

         How to model a pipe which has pores in its internal surface, when the pipe is filled with water and closed at the both ends. Now when the pipe is impacted in the 3 point bending mode water will enter in side the pores and will cause some damping (resist bending).
