Temperature-dependent transformation multiphysics and ambient-adaptive multiphysical metamaterials

EPL (Europhysics Letters), 2021
Temperature-dependent transformation thermotics provides a powerful tool for designing multifunctional, switchable, or intelligent metamaterials in diffusion systems. However, its extension to multiphysics lacks study, in which temperature dependence of intrinsic parameters is ubiquitous.

Multiphysics‐Informed Neural Networks for Coupled Soil Hydrothermal Modeling

Water Resources Research, 2022
Soil water and heat transport are two physical processes that are described by the Richardson–Richards equation and heat transport equation, respectively. Soil water and heat motion directly control transport or indirectly influence parameters.

Multiphysics Problems

2013
The formulation of different physical laws, in terms of algebraic operators, was presented in the previous chapters. From an analysis of the Tonti diagrams, it emerges that they are not related to a specific physical phenomenon, but they can be considered as a common framework for several theories, that is, a scaffolding into which the variables that ...
