The role of gouge production in the seismic behavior of rough faults: A numerical study
Miguel Castellano, Enrico Milanese, Camilla Cattania +1
Fault zones mature through the accumulation of earthquakes and the wearing of contact asperities at multiple scales. This study examines how wear-induced gouge production affects t…
Structural build-up at rest in the induction and acceleration periods of OPC
Luca Michel, Lex Reiter, Antoine Sanner +2
Structural build-up in fresh cement paste at rest is characterized by time evolutions of storage modulus and yield stress, which both increase linearly in time during the induction…
Mineral and cross-linking in collagen fibrils: The mechanical behavior of bone tissue at the nano-scale
Julia Kamml, Claire Acevedo, David Kammer
The mineralized collagen fibril is the main building block of hard tissues and it directly affects the macroscopic mechanics of biological tissues such as bone. The mechanical beha…
Energy dissipation in earthquakes
David S. Kammer, Gregory C. McLaskey, Rachel E. Abercrombie +10
Earthquakes are rupture-like processes that propagate along tectonic faults and cause seismic waves. The propagation speed and final area of the rupture, which determine an earthqu…

Eulerian framework for contact between solids represented as phase fields
Flavio Lorez, Mohit Pundir, David S. Kammer
Mechanical contact between solids is almost exclusively modeled in Lagrangian frameworks. While these frameworks have been developed extensively and applied successfully to numerou…
Advanced-Glycation Endproducts: How cross-linking properties affect the collagen fibril behavior
Julia Kamml, Claire Acevedo, David Kammer
Advanced-Glycation-Endproducts (AGEs) are known to be a major cause of impaired tissue material properties. In collagen fibrils, the main building component of human tissue, these…
Transonic and supershear crack propagation driven by geometric nonlinearities
Mohit Pundir, Mokhtar Adda-Bedia, David S. Kammer
Linear elastic fracture mechanics theory predicts that the speed of crack growth is limited by the Rayleigh wave speed. Although many experimental observations and numerical simula…
