Measurement of wear in LIGGGHTS

Submitted by b.saprativ on Tue, 03/10/2015 - 13:48

Hi

I was going through some tutorial in the website and found wear through a chute. Though it shows colors changing with time due to wear in the surface of the metal, the unit of wear is not there.

How much time it takes to develop a wear on a surface. Is it material dependent/time dependent/impact velocity dependent?

How do i understand the estimate of time of simulation to develop a wear on a surface. Any info regarding these will be helpful.

Thanks in advance.

Hi Saprativ,

You could google "LIGGGHTS wear" and it would show a PDF file to talk about the Finnie wearing model used in the LIGGGHTS.

Hi Saprativ,

the model is based on a variant of the Finnie wear model - it gives a qualitative idea of the wear. I would be very cautious in term of quantitative predicions, this will usually need a model tailored to the materials in question which is carefully calibrated by experiments.
