“…While woven materials show great potential in composites and other applications, a complete understanding of their governing mechanics is still evolving. Several researchers have contributed to the study of fabric behavior, most notably in the form of tensile testing [1^] and finite element modeling [5][6][7][8]. The work presented here expands on research previously published by the authors [9], which focused on defining the mechanical properties of a 325 x 2300 SS316L twill dutch woven wire mesh through uniaxial tensile experiments and main axes (warp and weft) finite element modeling.…”

“…Tarfoui and coworkers [6] employed finite elements to study an idealized fabric structure at the mesoscale, and ultimately utilized the model to make damage predictions. Other notable research efforts using finite elements to study mesoscale fabric behavior have been made by Cavellero and coworkers [5], Nicoletto and coworkers [7], and Barbero and co-authors [8]. The relatively large body of research in this area has proven FEM to be a reasonable approach to modeling complex fabric behavior, with a major limit being model size and inevitable boundary influence on model response.…”

Woven structures are steadily emerging as excellent reinforcing components in composite materials. Metallic woven meshes, unlike most woven fabrics, show high potential for strengthening via classical methods such as heat treatment. Development of strengthening processes for metallic woven materials, however, must account not only for behavior of the constituent wires, but also for the interactions between contacting wires. Yield behavior of a 325 x 2300 stainless steel 316L (SS316L) twill dutch woven wire mesh is analyzed via experimental data and 3D numerical modeling. The effects of short dwelltime heat treatment on the mechanical properties of this class of materials is investigated via uniaxial tensile tests in the main weave orientations. Scanning electron microscopy (SEM) is employed to investigate the effects of heat treatment on contacting wire interaction, prompted by observations of reduced ductility in the macrostructure of the mesh. Finally, the finite element method (FEM) is used to simulate the accumulation of plastic deformation in the mesostructure of the mesh, investigating how this wire level plasticity ultimately affects global material yielding.

“…It is well known that the mechanical properties of fabricreinforced composites are controlled by the fabric architecture, the fiber/matrix bonding and material properties of fiber and matrix [6,[10][11][12][13][14]17,23,24]. The fabric architecture depends upon the undulation, crimp, and density of the fiber tows.…”

“…These models predict the effects of the yarns and are more likely to closely describe crimp and shear effects. Mesoscale models developed by Assid [2], Barbero [3,4], Luo [5] and Boljen [6] treat yarn undulation as a sinusoidal function. Crimp interchange is modeled with either Eulerian or Timoshenko based beam bending.…”

A technique for modeling the tensile behavior and initial shape forming (weaving) process is presented in this paper. This technique uses FEA methods to model straight yarns as they are woven around each other. Tensile forces may be applied in subsequent load steps to predict the mechanics and strength of the fabric. This approach features innovative boundary conditions taking advantage of multiple levels of symmetry, thus allowing the model to be run using standard, unmodified FEA packages. As the model simulates the forming/weaving process it only requires data about the geometry and material properties of the yarns. This allows for fast characterization of hypothetical fabrics with no need for physical experimentation.Introduction. Woven fabrics and flexible composites are an important class of materials with a wide variety of uses. Flexible composites reinforced with woven fabric have many inherently positive characteristics, the potential for high strength, ease of use, and ease of lay-up in the forming process.Clothing, composite reinforcements, flexible composites, cloth structures, ballistic armors, parachutes, sails and numerous other applications make extensive use of woven fabrics. There is currently a large demand for lightweight military armor made of woven fiber flexible material. Here the large strains allow significantly higher energy absorption and dissipation than a stiff composite, as well as allowing for movement and articulation in the case of body armor. Prior to the curing process many rigid composites behave as flexible composite. The uncured matrix material is liquid and does not affect the structural properties, therefore the flexible woven fabric reinforcement will entirely determine the uncured structural properties. Understanding the mechanics of a composite material with an uncured matrix conforming to a tool shape could improve the lay-up process currently used within industry.Many biological structures, such as skeletal muscles consisting of striated fiber bundles suspended in an extracellular matrix, may be thought of as wavy fiber flexible composites and modeled accordingly.Modeling the mechanical behavior of this class of material presents a significant engineering challenge due to the geometric complexity of yarns undulating around each other. The yarns have a complex shape and may interact with yarns oriented in other directions. Mechanical properties may be both nonlinear and completely different under various loading conditions (uniaxial tension, biaxial tension, shear, bending, etc.).There are a number of different approaches to modeling the mechanics of woven materials. Modeling approaches are generally classified into three broad categories. Macroscale models treat the fabric as a continuum. Mesoscale models look at the effects of the yarns that are woven around each other, treating the yarns as a continuous material. Microscale models include the effects of the fibers that when bundled together comprise most yarns.Macroscale analytical models such as the model developed ...
