The mechanical properties of microscopic particles have been a heated research object for it takes the deformation of micro-beads in the microfluidic environment into account. Sufficient knowledge on mechanical properties of micro-beads would lead to better device design and application for cell mechanics, tissue engineering, etc. The physical properties of alginate beads were examined both in ...

in this paper, the effect of air relative humidity and capillary force on contact geometry of surfaces based on jkr model by atomic force microscopy was investigated in order to manipulate nano-particles. with transition from macro to nano-scale, the effect of surface forces becomes more significant in comparison with inertial force. because contact mechanics models are based on surface energy ...

The author demonstrates a stable Lagrangian solid modeling method, tracking the interactions of solid mass particles rather than using a meshed grid. This numerical method avoids the problem of tensile instability often seen with smooth particle applied mechanics by having the solid particles apply stresses expected with Hooke’s law, as opposed to using a smoothing function for neighboring soli...

Abstract Indentation techniques have proven to be effective characterize the mechanical properties of materials. For elastic deformation, commonly used models are Hertz model and Sneddon model. However, neither them works for indenting spherical samples using pyramid or conical indenter. Therefore, one modified has been developed determine Young’s modulus from indentation results. In this study...

Abstract Background Soft, biological, and bio-inspired materials are often compositionally heterogeneous structurally anisotropic, they frequently feature graded or layered organizations. This design complexity enables exceptional ranges in properties performance yet complicates a fundamental understanding of the contact mechanics. Recent studies soft gel layers have relied on Hertzian Winkler ...
