Creep failures in heterogeneous materials
H. Nechad, A. Helmstetter, R. El Guerjouma +1
We present creep experiments on fiber composite materials with controlled heterogeneity. Recorded strain rates and acoustic emission rates exhibit a power law relaxation in the pri…

Andrade and Critical Time-to-Failure Laws in Fiber-Matrix Composites: Experiments and Model
H. Nechad, A. Helmstetter, R. El Guerjouma +1
We present creep experiments on fiber composite materials. Recorded strain rates and acoustic emission (AE) rates exhibit both a power law relaxation in the primary creep regime an…

Self-Similar Law of Energy Release before Materials Fracture
V. I. Yukalov, A. Moura, H. Nechad
A general law of energy release is derived for stressed heterogeneous materials, being valid from the starting moment of loading till the moment of materials fracture. This law is…
