What is a non-uniform plastic deformation, and how does it occur?
Deformation is how a “body” or thing changes shape. It is almost always non-uniform, the exception being a uniform load applied to a shape without any form of stress concentrations - effectively a rectangular shape aligned with the load.
Now, plastic deformation is deformation that remains permanent after the load is removed. (And that deos not have rate-dependencies, viscous components.) Usually, there is a bit of elastic deformation occuring before the plasticity sets in. Thus, if the deformation is non-uniform (as it almost always is) then any plastic deformatiion occuring will also be non-uniform.
Of course, the trivial counterexample is when there is no plastic deformation (as when the load is below yield) - then the plastic deformation is uniformly zero everywhere.

Mainly by plastic deformation we infer permanent deformation, and it is 100% true.
There are many things which we can infer from plastic deformation
and many things…
