Fully Coupled Thermal Stress Analysis

Hi,

When I was reading the Abaqus manual about transient analysis in thermal field, I found a sentence that says 'In transient analyses using first-order elements the heat capacity terms are lumped, which eliminates such oscillations....' (Transient analysis in Abaqus Analysis User's Guide 6.5.3). 

I think that this 'oscillations' is related to not only explicit time integration, but also implicit time integration (such as Backward Euler method).

Hi,

Could anyone share some idea on how to model a Surface Coating. I am using Abaqus Standard for the thermal analysis. For the coating, i tried to create a 'Skin' on the surface and assigned a Homogenous Shell section for the Skin. Is this correct? I couldn't see much difference in the results. Or is there any better way to model a surface coating?

Thanks!!

Hi everyone,

I am new to ABAQUS. I am working on a research topic where I need to study the temperature increase arised due to strains applied to a body. From the user's manual I understood that I need to use "Sequentially Coupled Thermal-Stress Analysis" for my model.
