Abaqus UGENS/UMAT for composites damage

Submitted by ebarbero on Fri, 04/05/2013 - 10:06

A discrete damage mechanics (DDM) model is now available as a UGENS/UMAT implementation for Abaqus/standard. This is an analytic constitutive model for laminates composites, based on discrete fracture mechanics. It is capable of predicting matrix crack initiation and crack density evolution using just two parameters--the critical energy release rates (ERR) in opening mode I and shear mode II. A methodology is available to determine those (invariant) material properties from experiments.

hi.

Im modeling a composite with hashin damage.

but I dont know what to insert to the hashin damage

requirements .for example I dont know what to insert to the

fiber tensile strength or fiber compressive strength and so on. please help me

Applying constant strain as loading condition in Abaqus

Hello All:

I am running a simple thermal tension coupon test with two steps.

Step 1: Apply a 10 lbs load on the coupon at certain temp.

Step 2: Keep the strain constant and reduce temp ( the material would
try to contract but I must keep the strain constant by increasing load)

Is there a way for me to do step 2 in abaqus and have it predict the load or stress required to maintain constant strain?

I would appreciate your comments? Thanks

Hi,

I´m analizing the modes of a structure but I don´t know how to plot the different modes (I only see the first one). I´m using Adina 8.7.3.

Thank you very much!

Enquiry about modelling a cylinder filled with water in ABAQUS / CFD

Submitted by mayfly on Wed, 03/20/2013 - 14:55

Dear All

My name is Paula , I am new user in CFD coupled with ABAQUS. I would like to know and understand how can I simulate cell wall filled with of water. If the tank sloshing example good way to start with cfd/ABAQUS? .

The problem
is that the cytoplasm ( high % is water) has an internal pressure. I
would like to make the simulation with outside presure ( hydrostatic pressure)
and find which is the outside pressure to brake the cell
wall and the cytoplasm gets free.

Hello everybody.

I am doing my diploma project and I have to model an off-shore oil-rig in Abaqus. It's a metallic truss-type system. I've defined all of the elements composing the structure as wire elements and the decks as solids. Does anybody know how to define the contact between the decks and the supporting beams? The decks are supposed to be bolted to the beams.
