Description

The implementation of rigid and lightweight structures that perform support
functions has their main field of application in the industrial sector. These structures must
satisfy all requirements of security and comfort, besides being profitable for the company
using them, at the time of procurement and maintenance. This paper aims at studying
the behavior of expanded metal meshes subject to transverse loading, determining the
deflections produced by this type of loading. In this study, design recommendations for
the use and installation of expanded metal meshes provided by Standard EMMA 557-15 are
considered. Therefore, a finite element model is developed considering linear behavior
of material and geometry, employing the commercial software ANSYS. Solid elements
are used in the generation of the computational model where metal sheets are subject
to transverse loads to determine the deflections in the mesh. Next, the influence of the
following parameters is evaluated: material properties, span between structural supports,
magnitude and type of the transverse load (concentrated or uniform), size of pattern, and
orientation of the mesh. Finally, numerical results show that deflections found in expanded
metal meshes are clearly affected by the aforementioned parameters.
