In classical mechanical testing, determining the stress and strain states of complex shape specimens turns out to be very challenging, especially in most deformed regions. latter case, when not enough material is present, non-destructive testing needed for corresponding state. this study, a novel approach, based on local quasi-non-destructive instrumented indentation technique (IIT) coupled wit...

Abstract Sheet metal formed parts are often produced in multistage processes. The multi-directional deformations that occur this process pose a challenge for sufficiently accurate modeling of the material behavior. In paper, we present an experimental methodology and its potential serves as basis comprehensive validation models with respect to deformation. Therefore, results pre-strained DP600 ...

The strain aging and hydrogen embrittlement behavior of two bake hardening (BH) steels with different microstructures were investigated in this study. single-phase BH steel was composed fully ferrite, while the dual-phase consisted ferrite 3 % martensite. index (AI) measured to compare effect microstructure on behavior. As a small amount martensite is present steel, value higher than that AI sh...
