| Class | ADVANTAGES | DISADVANTAGES |
| I | none | does not lead to EVCP |
| II | EVCP for | PR is restricted to process with |
|
| only | a single time independent strain |
| III | leads to EVCP | equivalent PR in time space |
|
| for some cases | must be properly defined |
|
|
| as PR is path dependent |
| IV | none | nonlinear-no EVCP |
| V | none | no EVCP |
| VI | material dependent | no EVCP |
|
| but only for |
|
| VII | stress/strain independent | Eq. (32) makes use of |
|
|
| all PRs very CPU intensive |
| E, G, | stress independent unique | none |
| K, C | material property functions, |
|
|
| isothermal EVCP |
