Comparativo de modelagem de vigas de aço reforçadas com PRFC empregando elementos finitos de casca e elemento finitos sólidos tipo casca

Abstract

This work seeks, using modeling with the software ANSYS, show the possibility of replace the shell element SHELL181 with the solid-shell element SOLSH190 through numeric simulations in section I steel beams reenforced with Carbon Fiber Reinforced polymer (CFRP). In real world, all geometries are in three dimensions. The use of solid shell elements makes the process of mesh generation easier to analyze thin walls from 3D models of CAD softwares, with little pre-processing. Although, shell elements need to convert 3D geometries into planes, usually at the transversal section, and is very relevant the pre-processing before the infinite element model creation. Though the simulations un steel beams reenforced with CFRP and comparing to the results in literature, is very clear the possibility of replacement of shell elements with solid-shell elements, with a satisfactory accuracy, and, mainly because of the advantage of easier way to generate model’s mesh.
