Early Prediction of Creep Failure via Bayesian Inference of Evolving Barriers
Juan Carlos Verano-Espitia, Tero Mäkinen, Mikko J. Alava +1
Creep under a sustained load can persist for long times yet culminate in abrupt yielding or rupture, implying a finite lifetime even when the material appears solid. Here, we formu…
Strain-rate, temperature and size effects on the mechanical behavior of fiber bundles
Jerome Weiss
The mechanical characteristics of fibers (of various materials), as well as of fiber bundles, are of primary importance for the design and the mechanical behavior of textiles, or o…
Creep failure in heterogeneous materials from the barrier landscape
Juan Carlos Verano-Espitia, Tero Mäkinen, Mikko J. Alava +1
Stressed under a constant load, materials creep with a final acceleration of deformation and for any given applied stress and material, the creep failure time can strongly vary. We…
Effect of quenched heterogeneity on creep lifetimes of disordered materials
Juan Carlos Verano-Espitia, Jérôme Weiss, David Amitrano +2
We revisit the problem of describing creep in heterogeneous materials by an effective temperature by considering more realistic (and complex) non-mean-field elastic redistribution…
Investigating the relation between elastic and relaxation properties of dry, frictional granular media during shear deformation
Aurélien Rigotti, Véronique Dansereau, Jérôme Weiss
Using discrete element simulations based on molecular dynamics, we investigate the mechanical behavior of sheared, dry, frictional granular media in the "dense" and "critical" regi…
