Assessment of measuring errors in DIC using deformation fields generated by plastic FEA
TL;DR: In this paper, the influence of the adopted correlation function, the interpolation order, the shape function and the subset size on the derived displacements were investigated using numerically deformed images that were obtained by imposing finite element displacement fields on an undeformed image yielding plastic deformation of the specimen.
Journal ArticleDOI
Identification of the post-necking hardening behaviour of sheet metal by comparison of the internal and external work in the necking zone
TL;DR: In this paper, an alternative method to identify the post-necking hardening behavior of sheet metal without using a finite element model is presented, where the key point is the minimization of the discrepancy between the internal and external work in the necking zone during a tensile test.
Journal ArticleDOI
Identification of Post-Necking Hardening Phenomena in Ductile Sheet Metal
TL;DR: A combined theoretical/experimental approach accurately quantifying post-necking hardening phenomena in ductile sheet materials that initially exhibit diffuse necking in tension is presented in this paper, based on the minimization of the discrepancy between the internal and external work in the necking zone during a quasi-static tensile test.
Journal ArticleDOI
Analytical method to predict the pull-out strength of clinched connections
TL;DR: In this article, an analytical approach to estimate the pull-out strength is presented, along with the necessary assumptions and a correction curve is derived which enables to adapt the analytical solution accounting for bending effects.
