CALL FOR ABSTRACT: SES Symposium C-4: Mechanical Characterization of Soft Materials: Experiments and Modeling
Soft materials are ubiquitous in nature, from biopolymers, cells, and tissues to organs. In recent years, soft materials have been intensively explored in different engineering applications, ranging from haptic devices to soft robotics, from flexible electronics to biomimetic systems. Fundamental studies of the deformation mechanisms of soft materials and optimal designs in different applications urgently need robust methods for material characterization.
6th International Conference on MECHANICS OF BIOMATERIALS AND TISSUES
Dear all,
The 6th interntional conference on Mechanics of Biomaterials and Tissues will be in Hawaii. Please see the poster in the attachment. The dealine for submitting the abstract will be extended.

Diffusion-induced wrinkling instability in a circular poroelastic plate
A poroelastic material can imbibe solvent and swell. When the material swells inhomogeneously or
swells under external constraints, stresses can develop inside the material. The stresses can trigger
mechanical instabilities in the material or even break the material, which have been often observed
in experiments. In this paper, we study the wrinkling instability of a circular poroelastic plate, in
the process of solvent molecules migrating into the plate from the edge. The critical conditions for
wet adhesion between two soft layers
Two solids can adhere to each other in the presence of a liquid bridge between them, which is called wet adhesion. When the solid is soft, the liquid bridge can cause deformation in the material, and in turn, the deformation may have dramatic effects on the wet adhesion. To investigate the effect, in this article, we calculate the deformation in two soft layers with different separations and connected by a liquid bridge. We illustrate the effect of deformation in the soft layers on the adhesive force.
Drying-induced cavitation in a constrained hydrogel
Cavitation can be often observed in soft materials. Most previous studies were focused on cavitation in an elastomer, which is under different mechanical loadings. In this paper, we investigate cavitation in a constrained hydrogel induced by drying. With taking account of surface tension and chemo-mechanics of gels, we calculate the free energy of the system as a function of cavity size. The free energy landscape shows double-well structure, analogous to first-order phase transition. Above the critical humidity, a cavity inside the gel is tiny.
Faculty position in the department of mechanical and aerospace engineering at UCSD
The Department of Mechanical & Aerospace Engineering (MAE, http://maeweb.ucsd.edu/) at the Jacobs School of Engineering (JSOE) at the University of California, San Diego (UCSD), invites applications for a tenure-track faculty position at the Assistant/Associate/Full Professor rank with research focus on experimental and/or computational mechanics of advanced materials under extreme conditions.
