In order to examine the behavior of backfilled pillars, modeled pillar was set up and tested in the laboratory.
Backfilling improves the behavior of the pillar, increasing the Young's modulus, the peak stress and the residual stress.
The aim of this paper is to delve into the mechanisms involved in pillar failure as well as to investigate the non-linear behavior of rock pillars.
We then illustrate through three-dimensional device modeling that the photovoltaic behavior of these pillar-structured cells is essentially determined by these two morphological parameters.
We explore the flow stress and hardening behavior of micro-pillar sizes in the range 200 2000 nm at temperatures of 150 900 K.
We report on quantitative in situ transmission electron microscopy nanocompression tests used to study the deformation behavior of NiTi pillars on the nanometer scale.
Researchers from the National Institute for Occupational Safety and Health used a series of instruments (borehole extensometers, earth pressure cells, and embedment strain gauges) to study the post-failure behavior of two pillars confined by backfill in a test section at the Buick Mine near Boss, MO, USA.
To gain a comprehensive insight into superhydrophobic behavior, the roles of pillar height, width and spacing (or roughness and solid fraction), intrinsic CA, drop size, and vibrational energy are systematically investigated.
Microcompression tests on the as-fabricated and annealed pillars suggest that the FIB-induced defects, particularly dislocation loops, distinctively affect the deformation behavior of submicron Al pillars; while the yield and flow stresses appear unaffected by the annealing, strain bursts are larger and more frequent in the annealed pillars compared to those of as-fabricated samples.
The present results are expected to be useful in understanding the mechanical behavior of micron-sized pillars under pure tension and compression.
The present direct TEM observations contribute to the understanding of the nature of FIB-induced defects and reveal their distinct roles in the deformation behaviors of submicron pillars.
