SES 2024 Call for abstract: Structural signature of elasticity, plasticity, and fracture in disordered materials

Dear Colleagues,

The Annual Technical Meeting of the Society of Engineering Science will be held in Hangzhou, China, August 20-23. We would like to invite you to submit an abstract to our session (9.6) themed "Structural signature of elasticity, plasticity, and fracture in disordered materials", see detailed description below. The abstract can be submitted following this link and is due April 1st. Please feel free to reach out to us if you have any questions.

Description:

Materials like metallic glasses, granular materials, foams, and colloids feature a disordered packing structure of their constituent elements. These materials can develop rigidity through glass transition and jamming when stress is applied, or temperature is decreased. Understanding and modeling the deformation of disordered solids are often challenging because descriptions at the continuum-scale can fail to capture important physics at the length scale of a few particles, e.g., force chains and quasi-localized plastic particle rearrangement, especially for materials lacking a separation of length scales. To address this challenge, the role of the disordered packing structure in deformation needs to be uncovered. Key questions include: 

● how elastic-like response arises from the heterogeneous contact network of constituent particles

● how the disordered structure evolves during yielding and plasticity at large deformation and/or under periodic driving

● what role structural heterogeneity plays in the initiation and development of fracture in a disordered medium

This symposium aims to bring together experimental, computational, and theoretical research on a variety of disordered materials, with a focus on examining structural signatures in their mechanical response, which will provide insight for better mechanical models and design strategies for this family of materials.

Topics of interest include but are not limited to: laboratory characterization of structural evolution upon deformation, meso-scale elastoplastic modeling, non-local rheology, data-driven methods for structural analysis, fracture mechanics testing and modeling for disordered solids, strategies for actively manipulating material property via structure design.
