(Department of Theoretical and Applied Mechanics (UIUC), 200106)Insitu deformation studies in a transmission electron microscope equipped with an environmental cell have shown that solute hydrogen increases the velocity of dislocations, decreases the stackingfault energy, and increases ...

(Department of Theoretical and Applied Mechanics (UIUC), 200307)We use a continuum model to investigate the isochoric axial contraction and expansion of a right circular cylindrical specimen composed of a nematic elastomer that is crosslinked in a uniaxial state and then annealed. ...

(Department of Theoretical and Applied Mechanics (UIUC), 200401)We present a theory for the chemicallyinduced volume transitions of hydrogels. Consistent with experimental observations, we account for a sharp interface separating swelled and collapsed phases of the underlying polymer ...

(Department of Theoretical and Applied Mechanics (UIUC), 200305)By studying the asympototic connection between phasefield and sharpinterface theories for transitions between two phases distinguished only by their constant freeenergy densities, we show that the configurational force ...

(Department of Theoretical and Applied Mechanics (UIUC), 200110)We present a theory for uniaxial nematic elastomers with variable asphericity. As an application of the theory, we consider the timeindependent, isochoric extension of a right circular cylinder. Numerical solutions to the ...

(Department of Theoretical and Applied Mechanics (UIUC), 200111)Inspired by biological systems in which damage triggers an autonomic healing response, we have developed a polymer composite materials that can heal itself when cracked. This paper summarizes the selfhealing concept for ...

(20110525)Using geometrically based approaches, optimal characteristics of nonlinear flow networks were examined. The first model studied was that of a fractallike desalination plant. Solving the equations of diffusion by analogy ...

(Department of Theoretical and Applied Mechanics (UIUC), 200207)Working with the context of a theory proposed recently by Fried et al. (2001), we consider a onedimensional problem involving granular mixture of K > 2 discrete sizes bounded below by an impermeable base, above by an ...

(Department of Theoretical and Applied Mechanics (UIUC), 200302)Microencapsulated healing agents that possess adequate strength, long shelflife, and excellent bonding to the host material are required for selfhealing materials. Ureaformaldehyde microcapsules containing dicyclopentadiene ...

(Department of Theoretical and Applied Mechanics (UIUC), 200206)We use a continuum model to investigate the isochoric radial expansion of a right circular cylindrical specimen composed of a nematic elastomer that is crosslinked in a uniaxial state and then annealed. Numerical solutions ...
