150. S2508-ID-8200-Towards Mean-Field Potentials for Elastoplastic Composites

Martín I. Idiart (Universidad Nacional de La Plata (UNLP), Argentina)

11/13/25, 11:30 AM

More often than not, mean-field descriptions for random composites neglect microscopic interactions between elastic and plastic processes. They do so by homogenizing purely elastic and purely plastic deformations separately to compound them additively. While appealing simplifications in the structure of macroscopic constitutive relations naturally ensue, discomforting complications in...

The knowledge of mechanical properties of materials is based on a precise analysis of their relaxation spectra. The development of methods to deconvolve spectra from measured data, and the assessment of their reliability, is therefore of paramount importance. We present a novel Bayesian deconvolution method based on a physically grounded parameterization of the spectra. We use a Metropolis-...

153. S2508-ID-8354-Investigating precursors in complex systems: Insights from the Fiber Bundle Model and the 2017 Mexico Mw8.2 earthquake

Mariana Hamdan Padilha (Universidade Federal do Pampa (UNIPAMPA), Brasil), Leandro Ferreira Friedrich (Universidade Federal do Pampa (UNIPAMPA), Brasil), Ignacio Iturrioz (Federal University of Rio Grande do Sul (UFRGS), Brasil), Luis E. Kosteski (Universidade Federal do Pampa (UNIPAMPA), Brasil)

11/13/25, 12:10 PM

Complex systems are characterized by self-organization, where interactions among constituent elements give rise to emergent patterns and critical transitions. In geophysics, earthquakes can be interpreted within this framework, where the analysis of precursor parameters provides critical insights into impending systemic instabilities. Among these, the temporal evolution of the b-value, derived...

154. S2508-ID-8377-Formulación del problema de conducción del calor dn Materiales Funcionalmente Graduados (FGM) y sus aplicaciones

Juan C. Barreto (Universidad Nacional de Formosa, Formosa, Argentina), Mario A. Meza (Universidad Nacional de Formosa, Formosa, Argentina)

11/13/25, 12:30 PM

Los materiales funcionalmente graduados (FGM) son materiales compuestos no homogéneos en los que la composición del material y/o la microestructura cambian gradualmente a lo largo deuna o más direcciones, lo que conduce a una variación continua en las propiedades mecánicas, eléctricas y térmicas del material. Este cambio gradual en las propiedades, tales como las características...
