MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

We investigate the growth and remodeling of biological tissues, described as multi-constituent materials, and the structural evolution associated with these phenomena. We generalize the results obtained in [1, 2], and we frame them within the context of the Analytical Mechanics of nonholonomic systems. We do this to study growth variationally.

Inspired by [3, 4], we start from a...

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

The exploitation of instabilities within solids and structures has gained a lot of attention in recent years [1], with instabilities now being embraced in design rather than avoided. One potential application arises for micro-robotics within biological environments, where dynamic instabilities can be used to generate motion [2, 3].

This presentation investigates the possibility of...

136. The functional impact of myofiber macroscopic organization and disarray in computational models of the murine heart

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

A major challenge in computational models of cardiac electromechanics is the reconstruction of myocardial fiber architecture, as direct in vivo measurements of fiber orientation are not feasible. Consequently, rule-based methods are commonly adopted as surrogates, relying on empirical descriptions of fiber organization combined with patient-specific geometries. This study investigates the...

139. The mechanics of active fiber-reinforced plates: modeling curvature-induced cell alignment

Gabriele Fioretto (Politecnico di Torino)

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

Biological tissues frequently feature complex internal architectures, such as fiber networks, that strictly govern their mechanical behavior. Although the continuum mechanics of isotropic thin bodies incorporating biological effects, such as morphogenesis and internal activity, is well established $[1,2]$, a unified framework capturing anisotropy remains lacking.
This talk presents a rigorous...

146. Data-driven Discovery of Convex Dissipation Potentials in Viscoelasticity via Grammar-Based Symbolic Regression

Federico Califano (Sapienza University of Rome)

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

We propose a thermodynamically consistent, physics-informed symbolic-regression framework for the automated discovery of convex dual dissipation potentials in viscoelasticity. Within the generalized standard materials (GSM), we characterize internal-variable dynamics through a gradient flow $\dot z = (\varphi^{*})'(A)$ driven by the thermodynamic force $A = \partial \psi / \partial z$.
