Replication of mechanical testing in Ansys workbench
I am currently trying to replicate the mechanical testing performed on a fruit into the Ansys workbench. I have included fruit properties in ansys through applying stress strain curve under uniaxial compression test (for flesh only) & isotropic elasticity(for MOE and poission's ratio(for skin and flesh both).
I have created the geometry of the fruit in solidworks (assembly of plate, fruit(placed on the top of the plate and an indenter over the fruit). Please see the image below.
I have done basic simulation in static structural analysis through making plate surface as a fixed support and force application at the front most part of the indenter (which is touching the fruit skin). I applied constant force(load) and got this deformation data. But it is not similar to the mechanical testing condition.
Now I am finding methods for,
- how to apply loading conditions over time on the fruit through indenter ( I have data on load applied(kN) over time(s) on the avocado), (Force/remote force?)
- how to keep the indenter straight while moving it downward(as it moves downward at angle)
- how to apply force through indenter, to get the deformation only on the fruit. (as the loading analysis shows effect on the indenter also)
Any help/suggestions will be really helpful.
