This study investigates the effects of precompression and subsequent annealing on tensile deformation behavior a rolled AZ31 Mg alloy at room temperature using digital image correlation (DIC). When as-rolled sample (AR sample) is subjected to precompresssion along rolling direction (RD) transverse (TD), sample’s texture changes from typical normal (ND)-oriented basal RD- TD-oriented textures, r...

Phosphorene, a newly fabricated two-dimensional (2D) nanomaterial, has emerged as a promising material for biomedical applications with great potential. Nonetheless, understanding the wetting and diffusive properties of bio-fluids on phosphorene which are of fundamental importance to these applications remains elusive. In this work, using molecular dynamics (MD) simulations, we investigated the...

Diametral compression tests were performed on pultruded composite rods comprised of unidirectional glass or carbon fibers in a common matrix. During compression tests, acoustic emission (AE) activity was recorded and images were acquired from the sample for analysis by digital image correlation (DIC). In both composite systems, localized tensile strain developed in the transverse plane under th...

Because cell shape and alignment, cell-matrix adhesion, and cell-cell contact can all affect growth, and because mechanical strains in vivo are multiaxial and anisotropic, we developed an in vitro system for engineering aligned, rod-shaped, neonatal cardiac myocyte cultures. Photolithographic and microfluidic techniques were used to micropattern extracellular matrices in parallel lines on defor...

A self-built laser projection system for optical transverse strain measurements in tensile testing is presented. The setup based on diode modules, charge-coupled device array detectors, and standard optomechanical components proposed to be a low-cost polymer samples. mobile can easily mounted test machine. Circular cross-sectional changes diameter were detected with 10-μm resolution stress-stra...
