The 4th Symposium on Mechanics of Soft Materials and Tissues

Soft materials are important to a wide range of engineering and biomedical applications. Examples of soft materials include engineering polymers (rubbers, thermoplastics, and thermosets), active polymers (shape memory polymers and piezoelectric polymers), polymer composites, and soft tissues (cornea, arteries, skin). The mechanical behavior of soft materials is complex, often exhibiting large deformation, anisotropy, nonlinear inelasticity, and rate-dependent failure. The complex behavior of soft tissues and composites stems from a heterogenous microstructure, that can exhibit organization over multiple length scales. Further complicating matters, the behavior of soft active materials and tissues encompass multiple coupled physical phenomena such as themo-viscoelasticity, electro-elasticity, stress-driven transport, remodeling, and growth.
The goal of this symposium is to bring together researchers to share recent advances and inspire new concepts in the area of soft materials mechanics. Researchers are invited to present their recent work in constitutive modeling, finite element modeling, and experimental investigations of large deformation and inelastic behavior, multiphysics behavior, failure behavior, structure-function relationship, remodeling, and degradation of soft materials and material systems, and in particular of:
- Engineering polymers and polymer composites
- Active polymer and polymer composites such as shape memory polymers, environmentally responsive gels, and piezoelectric polymers
- Liquid crystal elastomers
- Polymer-based flexible macroelectronics
- Soft fibrous tissues, such as arteries, skin, and brain tissues
- Cells and cytoskeletal systems
