ABAQUS

Hi all,

I am trying to input a termperature field as initial conditions in

abaqus, to use the temperature distribution from a previous temperature

simulation in an mechanical simulation. But when I check the Temperature

values in the mechanical simulation i get great differences between the

nodal values (NT) and the element values (TEMP).

Does anybody know the reason of this problem?

Can it be related to the element typ? So the TEMP values are the avereged values from NT?

Hi everyone 

I am learning the polycrystalline crystal plasticity and testing material in ABAQUS and UMAT. Now I am trying to build a RVE by using the truncated octahedrons as the grain shape or Voronoi tessellations.

For truncated octahedrons, I built a truncated octahedrons and assembled them into the grain aggregate in the .inp file, and assign orientations in the UMAT based on the part's name. However, I found it hard to define their interaction between grains. What is their interaction properties and how to define the contact pair in an automatic way?

Hi

I am new to modelling and am trying to model a plate with a middle crack using Abaqus.

 What is the difference between modelling a cohesive and LEFM crack growth (I know cohesive involves plasticity and the traction/displacement curve and LEFM is for brittle materials).

 For cohesive, I used max principal stress for damage criteria and damage evolution based on energy criteria. 

Hello everyone. I am new to Abaqus and was wondering how to create a model of a heat sink mounted on a heated silicon dioxide substrate. The substrate is on the left side and is a rectangle with a height of 40 mm and width of 5 mm. The heat sink is connected to the right of that with a parrellelogram shape, left side height of 40 mm (adjacent to the substrate), and right side parallel with a height of 5 mm. If anyone can help it is greatly appreciated. When I try modeling it, during section assignments it will not allow me to assign any sections. I have attached a picture of the model.

I can't pipe down about this new Tech Brief!

Hi,

Is that possible to define an INTERIOR surface in Abaqus???

Hello ,

 I am working on a project using abaqus to
simulate miling process. As the first stage, I have to be able to simulate cutting process in Abaqus. I have looked up Abacus 6.11 documentaion a lot but did not find too much of usefull information. Could any one kindly give some hints how to develop such model or introduce me some usefull complete resources?

Regards,
