An anisotropic brittle damage model with a damage tensor of second order using a micromorphic approach Open

Marek Fassin, Robert Eggersmann, Stephan Wulfinghoff, Stefanie Reese · 2019

The work presents a gradient‐extended ansisotropic damage model for brittle materials utilizing a second order damage tensor. In order to take into account tension compression asymmetry (TCA), the strain tensor is split into a tension and …

Modeling of gradient-extended anisotropic damage using a second order damage tensor Open

Marek Fassin, Stephan Wulfinghoff, Stefanie Reese · 2019

Numerical simulations are indispensible in many engineering disciplines since they can reduce the number of costly and time-consuming experiments. For the prediction of material and structural failure, damage and fracture models have been …

Comparison of Multiscale Method of Cells-Based Models for Predicting Elastic Properties of Filament Wound C/C-SiC Open

Evan J. Pineda, Marek Fassin, Brett A. Bednarcyk, Stefanie Reese, Jaan‐Willem Simon · 2017

Three different multiscale models, based on the method of cells (generalized and high fidelity) micromechanics models were developed and used to predict the elastic properties of C/C-SiC composites. In particular, the following multiscale …

MODELLING THERMAL BARRIER COATINGS AND THEIR INFLUENCE ON THE LIFETIME OF ROCKET ENGINE NOZZLE STRUCTURES Open

Marek Fassin, Stephan Wulfinghoff, Stefanie Reese · 2016

The walls of rocket engine nozzle structures undergo extreme thermomechanical loadings during the engine cycle.These loads cause an accumulation of plastic strains due to creep and relaxation which finally lead to the failure of the hot ga…

Properties and Restrictions related to Anisotropic Damage Theories based on 2nd Order Damage Tensors Open
