Initial conditions

Thermomechanical coupled simulation

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?

 

Kind regards!

residual stress and strain definitions (through-thickness) in ABAQUS/Explicit

Choose a channel featured in the header of iMechanica: 

Hello everyone,

 

I need some help regarding the definition of initial residual stresses and plastic strains in a shell finite element (S4R) model in ABAQUS/Explicit.

I have determined the residual stress distributions and initial plastic strains and I need to assign these distributions to a given element set.

I understand I should be looking at:

*INITIAL CONDITIONS, TYPE=STRESS

 ELSET_A, S11, S22, S33

post tension in Abaqus

Hello,

 Am working on post tension prestressed concrete with Abaqus,

1-  I would like to know where to find the "initial conditions option and prestress hold" in which module??

2- Rebar option: as per the Help, it is mentioned that i can define a rebar as individual element not as rebar layer in a shell/membrane element. but also couldn't be able to find how and in which module?

Any suggestions?

Wating for a quick feedback

thanks
