Characterization of the tensile behavior of a metallic fiber woven structure

چکیده
The mechanics of a woven wire mesh material are investigated to characterize the elasto-plastic behavior of this class of materials under tensile conditions. The study focuses on a representative 316 L stainless steel (316 L SS) 325 2300 twill-dutch woven wire mesh typically used as a fine filtration media in applications such as water reclamation, air filtration, and as a key component in swab wands used in conjunction with explosive trace detection equipment. Mechanical experiments and a 3D finite element model were employed to study the macro-scale and meso-scale mechanical behavior of the woven wire mesh under uniaxial tensile conditions. A parametric study of the orientation dependence of the mechanical response of this material has been carried out, which relates material properties such as elastic modulus, yield strength, etc. to material orientation. Ratcheting type tensile tests are also performed in a similar orientation study, and an elementary damage model is presented for the woven wire mesh based on continuum damage mechanics. The elasto-plastic behavior of the wire mesh is studied via the finite element method, and observations are made relating localized plastic strain to remotely applied displacements.

Flow Behavior of SP-700 Titanium Alloy During Hot Tensile Deformation in α+β and β Phase Regions
In this paper, in order to study the flow behavior and elongation of as-cast ingots of SP-700 titanium alloy, hot tensile test was done in α/β dual phase and β single phase regions using strain rate of 0.1 s-1. Results showed that the hot tensile behavior of SP-700 in the α/β dual phase region (700-900 ºC) was different from the β single phase one (950-1100 ºC) due to the nature of alpha and be...
متن کاملModeling the Tensile Behavior of Fibers with Geometrical and Structural Irregularities
Virtually all fibers exhibit some dimensional and structural irregularities. These include the conventional textile fibers, the high-performance brittle fibers and even the newly developed nano-fibers. In recent years, we have systematically examined the effect of fiber dimensional irregularities on the mechanical behavior of the irregular fibers. This paper extends our research to include the ...
