Experimental Realization of the Fuse Model of Crack Formation
D. R. Otomar, I. L. Menezes-Sobrinho, M. S Couto
In this work, we present an experimental investigation of the fuse model. Our main goal was to study the influence of the disorder on the fracture process. The experimental apparat…
Anisotropy in Rupture Lines of Paper Sheets
I. L. Menezes-Sobrinho, M. S. Couto, I. R. B. Ribeiro
We have experimentally investigated the fracture process in paper samples submitted to a uniaxial force. Five types of paper sheets (newsprint, towel, sulfite, silk and couche pape…
Fracture toughness in fibrous materials
I. L. Menezes-Sobrinho
In the present paper, a fiber bundle model in (1+1)-dimensions that simulates the rupture process of a fibrous material pulled by an uniaxial force F is analyzed. In this model the…
Roughness exponent in the fracture of fibrous materials
I. L. Menezes-Sobrinho
In this paper, a computational model in (2+1)-dimensions which simulates the rupture process of a fibrous material submitted to a constant force , is analyzed. The roughness exp…
Failure regime in (1+1) dimensions in fibrous materials
I. L. Menezes-Sobrinho, A. T. Bernardes, J. G. Moreira
In this paper, we introduce a model for fracture in fibrous materials that takes into account the rupture height of the fibers, in contrast with previous models. Thus, we obtain th…
Scaling behaviour in the fracture of fibrous materials
I. L. Menezes-Sobrinho, J. G. Moreira, A. T. Bernardes
We study the existence of distinct failure regimes in a model for fracture in fibrous materials. We simulate a bundle of parallel fibers under uniaxial static load and observe two…
