Macro-scale roughness modelling

[FaroukM 22]

Hi everyone, 

 

Anyone here working on the modelling of the roughness / wear on macro-scale FEM model ? 

 

Best regards,

Do you want to input surface roughness for fatigue analysis?If so then you could use PFAT Bulk data entry to define same.

The idea is to perform macro-scale contact simulation (Non linear static analysis) with smooth surface that include roughness

Wear simulation is currently not possible with OptiStruct. Attached screenshot covers some highlights of OptiStruct 2019.1.

Thanks mate for your answer  

 

Another and the last question : There is an option in OptiStruct to implement, let's say, new finite element formulation or modify the formulation of the element ... ? (like development module in Abaqus) 

If yes, can you please send me the documentation ? 

 

Thank you again and have a nice weekend
