DOI: 10.1007/s00419-021-02026-9
Abstract: The Mullins effect is a characteristic property of filled rubber materials whose accurate and efficient modelling is still a challenging task. Innumerable constitutive models for elastomers are described in the literature. Therefore, this contribution gives… read more here.

DOI: 10.1016/j.cma.2018.06.013
Abstract: Abstract Local damage models with softening needs localization limiters to preserve the mathematical and physical consistency. In this paper we compare the properties of strain-gradient and damage-gradient regularizations. Gradient-damage models introduce a quadratic dependency of… read more here.

DOI: 10.1016/j.ijsolstr.2017.04.038
Abstract: Abstract The field of continuum damage mechanics addresses mathematical models for the degradation of the mechanical properties of engineering materials, in particular for softening effects. It is therefore reasonable to define what ’degradation of properties’… read more here.

DOI: 10.1016/j.tafmec.2019.102440
Abstract: Abstract Despite the versatility in modeling complex crack configurations, phase-field damage models for fracture usually count only on in-house codes, greatly restricting their potential applications. It is thus of vital importance to implement them in… read more here.

DOI: 10.5194/nhess-20-2997-2020
Abstract: Effective flood risk management requires a realistic estimation of flood losses. However, available flood damage estimates are still characterized by significant levels of uncertainty, questioning the capacity of flood damage models to depict real damages.… read more here.
