Symposium description
As engineering systems are increasingly designed at smaller scales or incorporate complex microstructures, conventional material models often fall short in predicting observed behaviors. Notably, many materials exhibit mechanical responses that vary with size, necessitating advanced modelling strategies that go beyond classical continuum mechanics. This symposium centers on the development and application of models that explicitly incorporate length-scale effects into material behavior, from theory to simulation and experimental validation.
We welcome contributions that explore new theoretical formulations, numerical techniques, and multiscale frameworks tailored to size-dependent phenomena. Topics of interest include, but are not limited to:
- Continuum models incorporating internal length scales, such as strain gradient and micromorphic theories
- Computational strategies for simulating size-dependent responses in complex materials
- Links between microscale mechanisms (e.g., dislocation behavior, microstructure evolution) and macroscopic models
- Applications to materials and structures where size effects play a critical role in performance, including those involving damage, fracture, localization, and wave propagation
- Determination of constitutive parameters, specific to size dependent models, from relevant small-scale experiments
