most published results about the characteristics of niti wires are based on the mechanical laboratory tests on the as-received wires.the purpose of this study was to investigate the effect of saliva on load-deflection characteristics of superelastic niti wires.in this experimental study, 15 wires of three kinds of superelastic niti wires (sentalloy, force i and truflex) were prepared. five spec...

Lightweight core topologies have been considered as an advanced alternative to improve the overall performance of sandwich structures in bending. Designed beams containing 3D printed cores conventional honeycomb, re-entrant auxetic honeycomb with two positions cells, and chiral were created CATIA V5. The manufactured from polylactic acid polymer (PLA) by fused deposition modeling (FDM) using Ul...

Dynamic three-point bend tests are performed on small beams specimen made of a quasi-brittle material. The most classical hypotheses needed to analyse the tests with SHPB, which are based on a state of quasi-static balance of the body, cannot be used. In order to get the behaviour it is necessary to perform a transient analysis of the specimen response. In most cases, the useful duration of the...

The mechanical properties of thick-walled SiO2 nanotubes (NTs) prepared by a sol-gel method while using Ag nanowires (NWs) as templates were measured by using different methods. In situ scanning electron microscopy (SEM) cantilever beam bending tests were carried out by using a nanomanipulator equipped with a force sensor in order to investigate plasticity and flexural response of NTs. Nanoinde...
