Book Description :

Hydrogels consist of cross-linked polymer chains and water molecules. Due to the coupling between deformation of the polymer network and diffusion of the solvent molecules, the fracture behavior of hydrogels is quite different from that of polymers and rubbers. This dissertation presents theoretical and numerical studies on fracture behavior of hydrogels with linear and nonlinear theories. For the study of stationary cracks, a centered crack model is used for hydrogel specimens under the plane strain condition. Asymptotic analysis of the crack tip fields is presented based on a linear poroelastic formulation for different chemical boundary conditions (immersed and not-immersed). For both cases, a finite element method is developed under different mechanical loading conditions (displacement-control and load-control). The evolution of the crack-tip energy release rate is calculated by a modified path-independent J-integral that takes the effect of energy dissipation due to solvent diffusion into account. Numerical results agree well with the asymptotic solutions of the crack-tip fields. Under load control, the crack-tip energy release rate increases over time, which suggests the onset of crack growth may be delayed until the crack-tip energy release rate reaches a critical value (fracture toughness). For steady-state crack growth of hydrogels, a semi-infinite crack in a long strip specimen subject to plane-strain loading is studied with both asymptotic and numerical analysis. The crack-tip energy release rate is found to be smaller than the applied energy release rate due to poroelastic shielding. The characteristic size of the poroelastic crack-tip field is inversely proportional to the crack speed. For relatively fast crack growth, the crack-tip energy release rate decreases with increasing crack speed. For relatively slow crack growth, the energy release rate increases with increasing crack speed. The present results are found to be qualitatively consistent with previous experiments on the effects of velocity toughening, solvent viscosity and crack-tip soaking. Moreover, the effect of plane stress is examined with a cohesive zone model. Finally, the nonlinear effect due to large deformation is studied numerically based on a nonlinear poroelastic model

Book Description :

Double-network (DN) hydrogels developed by Gong et al. (Advanced Materials 2003, 15, 1155) are interesting polymeric materials that despite their large water content (ca. 90 wt%) possess excellent strength and toughness. Those gels can undergo large deformations and exhibit intriguing mechanical behavior such as necking in tensile loading and idealized Mullins effect. DN hydrogels are the product of free radical polymerization of a water-soluble monomer like acrylamide (AAm) inside a highly crosslinked polyelectrolyte network like poly(2-acrylamido-2-methylpropsnesulfonic acid) [poly(AMPS)]. That polymerization process can be done with or without using a cross-linking monomer. Therefore, DN hydrogels were first thought to be interpenetrating polymer networks (IPNs) or semi-IPNs (SIPNs).The main objective of this dissertation was to understand the structure-property relationships in DN hydrogels and develop a model to capture their mechanical behavior.The experimental part of this study involves synthesis and characterization of tough chemically crosslinked hydrogels based on the DN concept and performing mechanical tests on them. A physical picture was developed to describe necking phenomenon in DN hydrogels. It was found that the necking phenomenon is triggered by the damage of the first network and necking occurs at the onset of load transfer from the first network to the second one. By providing experimental evidence, it was discovered that in DN hydrogels there is a covalent grafting between first and second networks and more importantly that grafting is necessary for achieving toughness. Therefore, DN hydrogels are not true IPN or SIPN structures and depending on whether crosslinking agent is used in the second polymerization step or not, the actual microstructure of a tough DN hydrogel is either a pseudo-IPN or pseudo-SIPN, respectively, where the prefix pseudo denotes connectivity of the two networks. Crack propagation and finite tensile deformation of DN hydrogels with pseudo-SIPNs and pseudo-IPNs architectures were compared. Moreover, the effect of polymerization of a third loosely crosslinked network inside a DN hydrogel was studied and discussed.In the theoretical part, a continuum damage model was developed to describe the large strain damage elasto-plastic behavior of DN hydrogels under tensile loading. The model was formulated by developing a physical picture of fracture process and incorporating a damage variable to a strain energy density function. The model is consistent with the experimental data and can capture the elasto-plastic behavior of the material without using a yield function. It was shown that a dimensionless parameter which is a ratio of two material parameters controls the behavior of the material. Those material parameters can be related to the elastic moduli of the first and second networks and in a fundamental level can be attributed to the crosslink densities of the first and second networks. The model can capture the stable branch of material response during necking when the engineering stress becomes constant during neck propagation.

Book Description :

The science of mathematical modelling and numerical simulation is generally accepted as the third mode of scienti?c discovery (with the other two modes being experiment and analysis), making this ?eld an integral component of c- ting edge scienti?c and industrial research in most domains. This is especially so in advanced biomaterials such as polymeric hydrogels responsive to biostimuli for a wide range of potential BioMEMS applications, where multiphysics and mul- phase are common requirements. These environmental stimuli-responsive hydrogels are often known as smart hydrogels. In the published studies on the smart or stimu- responsive hydrogels, the literature search clearly indicates that the vast majority are experimental based. In particular, although there are a few published books on the smart hydrogels, none is involved in the modelling of smart hydrogels. For the few published journal papers that conducted mathematical modelling and numerical simulation, results were far from satisfactory, and showed signi?cant d- crepancies when compared with existing experimental data. This has resulted in ad hoc studies of these hydrogel materials mainly conducted by trial and error. This is a very time-consuming and inef?cient process, and certain aspects of fun- mental knowledge are often missed or overlooked, resulting in off-tangent research directions.

Book Description :

The past few decades brought a revolution in computer software and hardware; today we are on the cusp of a materials revolution. If yesterday we programmed computers and other machines, today we program matter itself. This has created new capabilities in design, computing, and fabrication, which allow us to program proteins and bacteria, to generate self-transforming wood products and architectural details, and to create clothing from "intelligent textiles" that grow themselves. This book offers essays and sample projects from the front lines of the emerging field of active matter. Active matter and programmable materials are at the intersection of science, art, design, and engineering, with applications in fields from biology and computer science to architecture and fashion. These essays contextualize current work and explore recent research. Sample projects, generously illustrated in color, show the range of possibilities envisioned by their makers. Contributors explore the design of active material at scales from nano to micro, kilo, and even planetary. They investigate processes of self-assembly at a microscopic level; test new materials that can sense and actuate themselves; and examine the potential of active matter in the built environment and in living and artificial systems. Active Matter is an essential guide to a field that could shape the future of design.
