First, an asymmetric failure behavior has been implemented to avoid compression failure
of cohesive elements.
Among the topics are a numerical study of adsorption enhancement by nanoparticle-scale inhibitor, reusing byproduct alumina composite powder from a hydrogen production process, electrospun cellulose acetate fiber containing rubber extract, a solid state welding process for aerospace components, and a numerical study on uni-axial compression failure
in brittle material with a single flaw.
Any reinforcement ratio above this value leads to a primary concrete compression failure
, while any reinforcement ratio below the balanced ratio indicates a rebar rupture failure.
We present three metrics: segment count, compression efficiency and compression failure number, which can demonstrate the transmission performance of the TCP compression schemes systematically.
Therefore, the compression ratio estimation based on Karlman Filter helps to increase compression efficiency and decrease compression failure number in the TCPComp scheme.
A compression failure finally occurred adjacent to the load which may be designated as a shear compression failure.
The failure of the beams at lower a/d ratios was observed to be diagonal compression failure.
At this state we will have a failure, with compression failure
in the concrete strut and yielding in the shear reinforcement.
Over the last two decades, significant attempts have been focused in understanding the compression failure
mechanisms as well as to improve the compressive properties of ri gid-rod polymeric fibers (9-19).
The application of double mesh strengthening to the bottom fibers is not justified, because the expected compression failure
will initiate at the top fibers before reaching the full strength of the double CFRP strips.
No compression failures
were noted at the third reaction points.
