Can Local Stress Enhancement Induce Stability in Fracture Processes? Part II: The Shielding Effect
Jonas T. Kjellstadli, Eivind Bering, Srutarshi Pradhan +1
We use the local load sharing fiber bundle model to demonstrate a shielding effect where strong fibers protect weaker ones. This effect exists due to the local stress enhancement a…

Variation of elastic energy shows reliable signal of upcoming catastrophic failure
Srutarshi Pradhan, Jonas T. Kjellstadli, Alex Hansen
We consider the Equal-Load-Sharing Fiber Bundle Model as a model for composite materials under stress and derive elastic energy and damage energy as a function of strain. With grad…

Can Local Stress Enhancement Induce Stability in Fracture Processes? Part I: Apparent Stability
Jonas T. Kjellstadli, Eivind Bering, Martin Hendrick +2
By comparing the evolution of the local and equal load sharing fiber bundle models, we point out the paradoxical result that stresses seem to make the local load sharing model stab…
