thermal radiation analysis in ansys workbench 12

Submitted by whyakhan on

Hello everybody,

I have been assigned the task of performing thermal analysis of electronic components that involve conduction and radiation only and determine the temperature distribution on them. I am doing this in ansys workbench 12. Since I am doing thermal analysis for the first time so having problems.

Does anybody have tutorials related to performing thermal analysis in ansys workbench. Please share.

Thanks in advance.

Regards,

Effects of mismatch strain and substrate surface corrugation on morphology of supported monolayer graphene

Submitted by Rui Huang on

In a previous work, substrate-modulated morphology of graphene was analyzed using a numerical Monte Carlo method. Here we present an analytical approach that explicitly relates the van der Waals interaction energy to the surface corrugation and the interfacial properties. Moreover, the effect of mismatch strain is considered, which predicts a strain-induced instability under a compressive strain and reduced corrugation under a tensile strain.

Subsea Integrity

Submitted by Henry Tan on

I am teaching Subsea Integrity for the MSc students majoring in Subsea Engineering at the School of Engineering, University of Aberdeen. This is a course that combines the fundamental principles (corrosion, fracture, fatigue and material selection) with the industry applications (subsea integrity management and implementation, cathodic protection, case studies on subsea reliability and engineering assurance).

question about Gurson model

Submitted by Reza_Rastgar on

I have a question regarding Gurson model. If we have a cube with initial length of unit and initial porosity of 20 percent and compress it hydrostatically in order to have a huge volume change of cube, the void growth equation in Gurson model takes a negative rate and reduces the void volume fraction to zero first and further compressing leads to no further void volume fraction change (remains zero) and no more plastic straining. Now let's load the model in tensile hydrostatic state up to a stress free configuration; the void volume fraction of the model remains zero.

Thermal stresses from pre-defined temperature data (thermography image)

Submitted by Aitor Garcia on

I´m facing a problem in which a I´d like to assess stresses due to thermal gradients. I have an IR thermography image (recorded as a matrix) and I like to introduce those temperatures to Abaqus via Matlab.

Is that possible? Or should I use FORTRAN with the UTEMP subroutine?

Thanks in advance,
