Regularization for the inversion of Fibre Bragg Grating spectra
Daniel Gerth, Susann Hannusch, Oliver Ernst +1
Fibre Bragg Gratings have become widespread measurement devices in engineering and other fields of application. In all but a few cases, the relation between cause and effect is sim…
Evaluation of hyperelastic models for unidirectional short fibre reinforced materials using a representative volume element with refined boundary conditions
N. Goldberg, H. Donner, J. Ihlemann
The simulation of a short fibre reinforced structure by means of the FEM requires the knowledge of the material behaviour at every Gauss point. In order to obtain such information,…
On the thermodynamics of pseudo-elastic material models to reproduce the Mullins effect
Christoph Naumann, Jörn Ihlemann
This work focuses on the thermodynamics of pseudo-elastic models which represent the Mullins effect. Two established models are analyzed theoretically, their thermomechanical prope…
Ductile damage model for metal forming simulations including refined description of void nucleation
A. V. Shutov, C. B. Silbermann, J. Ihlemann
We address the prediction of ductile damage and material anisotropy accumulated during plastic deformation of metals. A new model of phenomenological metal plasticity is proposed w…
Experimental determination and modelling of volume shrinkage in curing thermosets
Martin Rudolph, Martin Stockmann, Ralf Landgraf +1
This work deals with the characterisation and modelling of the curing process and its associated volume changes of an epoxy based thermoset resin. Measurements from differential sc…
Analysis of some basic approaches to finite strain elasto-plasticity in view of reference change
A. V. Shutov, J. Ihlemann
There is a large variety of concepts used to generalize the classical Prandtl-Reuss relations of infinitesimal elasto-plasticity to finite strains. In this work, some basic approac…
Modelling and simulation of adhesive curing processes in bonded piezo metal composites
Ralf Landgraf, Martin Rudolph, Robert Scherzer +1
This work deals with the modelling and simulation of curing phenomena in adhesively bonded piezo metal composites which consist of an adhesive layer with integrated piezoelectric m…
On the phenomenological modelling of yield surface distortion
Alexey Shutov, Jörn Ihlemann
A simple phenomenological approach to metal plasticity, including the description of the strain-induced plastic anisotropy, is considered. The advocated approach is exemplified by…
Modelling and simulation of acrylic bone cement injection and curing within the framework of vertebroplasty
Ralf Landgraf, Jörn Ihlemann, Sebastian Kolmeder +3
The minimal invasive procedure of vertebroplasty is a surgical technique to treat compression fractures of vertebral bodies. During the treatment, liquid bone cement gets injected…
An explicit solution for implicit time stepping in finite strain viscoelasticity
Alexey V. Shutov, Ralf Landgraf, Jörn Ihlemann
We consider the numerical treatment of one of the most popular finite strain models of the viscoelastic Maxwell body. This model is based on the multiplicative decomposition of the…
On a dislocation density based two-phase plasticity model: refinement and extension to non-proportional loading
C. B. Silbermann, A. V. Shutov, J. Ihlemann
The two-phase composite approach of Estrin et al. (1998) describes an evolving dislocation cell structure. Mckenzie et al. (2007) enhanced the model to capture the effects of hydro…
A viscoplasticity model with an enhanced control of the yield surface distortion
A. V. Shutov, J. Ihlemann
A new model of metal viscoplasticity, which takes combined isotropic, kinematic, and distortional hardening into account, is presented. The basic modeling assumptions are illustrat…
