In Ansys Mechanical, Equivalent Plastic Strain is available as an output. Here, Equivalent strain, as the name is calculated as per the Von-Mises equations .(more on that from the resources mentioned below.)
So, deformation is associated with the given load, but when the load is removed and the stress lies in the elastic region, strain will cause the deformation to nullify.
Engineering Strain is the ratio of deformation experienced by the body in the direction of force to the original length. One lying in Plastic region of stress strain curve are plastic strains which cause a permanent deformation per length.
Interpreting from the simulation, 0.58253 is the equivalent strain, which represents any 3 dimensional state to a positive value.

Hope that helps.
