Description

Predicting effective mechanical properties of composite materials and structures remains one of the major challenges in the field of multiscale modeling. The mechanical response and damage behavior at higher length scales are deeply influenced by processes at lower length scales, governed by the interaction among the composite constituents (matrix, fibers, laminae, interphases, etc.). Moreover, while at the continuum scale there are methodologies available to determine the condition for crack nucleation and propagation in homogeneous materials, analogous techniques remain inadequate in the context of effective strength and toughness of brittle composites. Thus, the development of reliable models, taking into account multiple scales and field actions, plays a crucial role in the analysis, design, evaluation and optimization of these materials.

The symposium invites researchers and scientists in the broad areas of multiscale modeling of conventional and advanced composite materials and their constituents, with a focus on the mechanical behavior, damage response, fracture and evaluation of the strength and toughness of these materials, using novel analytical and computational multiscale approaches.
We invite abstracts on theoretical, computational and integrated computational-experimental modeling techniques from scientists (including mathematicians, physicists, engineers) working in different fields of material science and mechanics of materials.

Topics to be covered include, but are not limited to, the following:
• multi-scale modeling of interphases, thin films and surfaces, traction laws
• models of imperfect, sliding, debonding or cohesive interfaces in composite materials
• deformation, damage, fracture and other dissipative processes at interfaces
• advanced finite element methods for the computational modeling of interfaces and surfaces
• fracture and damage in a multi-physics framework (e.g coupling with plasticity, thermal and chemical effects, etc.)
• 1D nanocomposites such as composite nanowires, 2D composites including planar and van der Waals heterostructures, and 3D composites including carbide-carbide composites, carbide-boride composites, oxide composites
