Strict upper bounds of the error in calculated outputs of interest for plasticity problems

This paper introduces a new computational technique for deriving guaranteed upper bounds of the error in calculated outputs of interest for plasticity problems under quasi-static conditions. This approach involves the resolution of some nonstandard additional problems, for which resolution techniques are given. All sources of error (spatial and temporal discretization, iteration stepping) are taken into account.

► New computational technique to get guaranteed local error upper bounds introduced. ► Computed outputs of interest for plasticity problems. ► Techniques for solving non standard additional problems are given.
