Article Synopsis
  • Focused Ion Beam (FIB) is widely used for fabricating nanodevices, but its effects on the mechanical properties of polymers have not been fully understood until now.
  • The study used a transmission electron microscope to observe the bending of FIB-milled epoxy nanobeams, finding significant changes in strength and brittleness due to gallium ion irradiation.
  • Results indicated that the FIB process increases the flexural strength and alters the elastic properties of the epoxy, opening up possibilities for better polymer applications in nanoscale devices and soft materials.

A unique three-dimensional (3D) computational multiscale modeling approach is proposed to investigate the influence of presence of microcalcification particles on the stress field distribution in the thin cap layer of a coronary atherosclerotic vulnerable plaque system. A nested 3D modeling analysis framework spanning the multiscale nature of a coronary atherosclerotic vulnerable plaque is presented. At the microscale level, a micromechanical modeling approach, which is based on computational finite-element (FE) representative unit cell, is applied to obtain the homogenized nonlinear response of the calcified tissue.

Chitosan hydrogels (CHs) have been considered as a potential implant material for replacement and repair of the Nucleus Pulposus (NP) within the intervertebral disk. The nonlinear mechanical behavior of a CH material is investigated experimentally and computationally in this study. A series of confined and unconfined compression tests are designed and conducted for this hydrogel.
