Tunable failure: control of rupture through rigidity
Michelle M. Driscoll, Bryan Gin-ge Chen, Thomas H. Beuman +3
We investigate how material rigidity acts as a key control parameter for the failure of solids under stress. In both experiments and simulations, we demonstrate that material failu…
Shear shocks in fragile networks
Stephan Ulrich, Nitin Upadhyaya, Bas van Opheusden +1
A minimal model for studying the mechanical properties of amorphous solids is a disordered network of point masses connected by unbreakable springs. At a critical value of its mean…
Force-extension relation of cross-linked anisotropic polymer networks
Panayotis Benetatos, Stephan Ulrich, Annette Zippelius
Cross-linked polymer networks with orientational order constitute a wide class of soft materials and are relevant to biological systems (e.g., F-actin bundles). We analytically stu…
Stability of freely falling granular streams
Stephan Ulrich, Annette Zippelius
A freely falling stream of weakly cohesive granular particles is modeled and analysed with help of event driven simulations and continuum hydrodynamics. The former show a breakup o…
Jammed frictional tetrahedra are hyperstatic
Max Neudecker, Stephan Ulrich, Stephan Herminghaus +1
We prepare packings of frictional tetrahedra with volume fractions ϕ ranging from 0.469 to 0.622 using three different experimental protocols under isobaric conditions. Analysis vi…
Random networks of cross-linked directed polymers
Stephan Ulrich, Annette Zippelius, Panayotis Benetatos
We explore the effect of random permanent cross-links on a system of directed polymers confined between two planes with their end-points free to slide on them. We treat the cross-l…
