In practice, concrete compression strength is used to compute the elastic modulus of concrete. For this calculation, various formulations are given in different codes. For a given concrete compressive strength, elastic modulus values calculated using different equations given in the codes could vary. In the present study, upper and lower boundaries of elasticity modulus are calculated using fuz...

Many real-world examples of fluid-structure interaction, including the transit of red blood cells through the narrow slits in the spleen and the intracellular trafficking of vesicles into dendritic spines, involve the near-contact of elastic structures separated by thin layers of fluid. Motivated by such problems, we introduce an immersed boundary method that uses elements of lubrication theory...

We investigate hysteretic behavior in two dynamic models for solid-solid phase transitions. An elastic bar with a nonconvex double-well elastic energy density is subjected to time-dependent displacement boundary conditions. Both models include inertia and a viscous stress term that provides energy dissipation. The first model involves a strain-gradient term that models interfacial energy. In th...

To characterize the complex morphological variations that occur naturally in human neuroanatomy so that their confounding eeect can be minimized in the identiication of brain structures in medical images, a computational framework has evolved in which individual anatomies are mod-eled as warped versions of a canonical representation of the anatomy, known as an atlas. To realize this framework, ...

Non-180° ferroelectric domains are also ferroelastic domains; their existence in polycrystalline materials is to relieve internal stresses generated during solid-solid phase transitions and minimize the elastic distortion energy. Therefore, grains with random orientations in polycrystalline ceramics are always occupied by many domains, especially in the regions close to grain boundaries. In thi...

The plane-strain bulge test is used to investigate the mechanical behavior of freestanding electroplated Cu thin films as a function of film thickness and microstructure. The stiffness of the films increases slightly with decreasing film thickness because of changes in the crystallographic texture and the elastic anisotropy of Cu. Experimental stiffness values agree well with values derived fro...

Mesoscale models are used to study dynamic deformation and failure in silicon carbide (SiC) and aluminum oxynitride (AlON) polycrystals. Elastic and anisotropic elastic-plastic crystal models represent mechanical behavior of SiC and AlON and grains, respectively. Cohesive zone models represent intergranular fracture. Failure data that can be used to inform macroscopic continuum models of cerami...

When a water drop hits a superhydrophobic solid surface, it bounces off the substrate like an elastic ball. Here we show that when a tiny superhydrophobic solid sphere impacts with water, it can bounce off the free surface just as it impacts with an elastic membrane. The motion of a sinking sphere is analytically calculated by solving a potential flow whose free boundary is determined by the Yo...

For multicomponent vesicles, the line tension of domain boundaries and the component-dependent elastic properties (e.g., spontaneous curvatures) are the two most important factors that mediate the budding behaviors of these vesicles. This paper especially focuses on their effects on the budding types and the budding number of a two-component vesicle. We found that the budding number is mainly d...

[1] We identify sites of apparent flexural uplift at rift zone boundaries on Ganymede using Galileo stereo-derived topography. The estimated effective elastic thickness te is 0.9–1.7 km for a nominal Young’s modulus of 1 GPa. Using a viscoelastic model of the ice crust we find that the temperature defining the base of the elastic layer is <185 K for likely strain rates. The inferred local heat ...
