I am a student of Mtech in CAD/M from MNNIT allahabad ,INDIA.....final semester.
For my thesis i have to simulate erosion of coatings under sigle particle impact.
scheme is that there is a metallic substrate.
we bombard the surface with a rigid sphere (erodent) from a certain height with certain height
its impact causes stress in substrate material. peak stress and stress distrubation is noted.
now we add coating to the substrate. coating thickeness is of micro-meter order.
again we bomabard it with a single particle.
now pesk stress and distribution is again noted and difference in both cases is the object of interest.
it can be done in 2-D and 3-D both .
also if possible to model erosion rate ie ration of mass of material removed and mass of erodent particle..(w/w).
if possible please help me.
as far as i knew...in it contact pair option has to be used both in ANSYS or ABAQUS.
MOSTLY it is done IN ABAAQUS/Explicit..dynamic modelling.....
I do not know more than that so i m sending this to u for help.
hope a early reply.
