TL;DR: In this article, a high-pressure x-ray photoelectron spectroscopy system dedicated to probing catalytic reactions under realistic conditions at pressures of multiple bars is presented, which can be used to obtain high-resolution images of catalytic reaction reactions.

TL;DR: In this article, a phenomenological uniaxial model is derived for implementation in the time domain, which captures the amplitude and frequency dependency of filled elastomers, motivated by the experimental observation that the frequency dependency is stronger for smaller strain amplitudes than for large ones.

TL;DR: An efficient methodology for obtaining hyperelastic material parameters for filled elastomers utilizing unloading curves in uniaxial tension, pure shear and the inflation of a rubber membrane is presented in this paper.

TL;DR: In this article, a three dimensional viscoplastic constitutive model for finite strains in a co-rotational explicit scheme is developed and implemented using finite elements that capture the amplitude dependency, and it is shown that the model captures the amplitude dependence of the amplitude.

TL;DR: In this article, a modal shape filter is used to control the test such that the shapes that are generating stress in critical points are reproduced, and a selective weighting of the mode shapes allows for accurate reproduction of the stress and hence the damage, also in circumstances when the exact location of the excitation force cannot be reconstructed in the test.
