Abstract
In this work, we present a comparison between the experimental results of tensile tests and computational simulations performed with Finite Element Method. The use of Finite Element Method to simulate composite materials is a recent development that has low use when compared to simulations of metal structures. There are several approaches to using the Finite Element Method in the simulation of structures of composite materials, but the influence of the laminating technique is still little known. This work reduces this gap with a discussion about the influence of the consideration of lamination techniques in the computational simulation. Experimental results include tests with specimens fabricated using manual lamination, vacuum lamination and infusion. It was observed that the FEM simulation using shell multi-layer elements showed an average of 3,6% of variation and using solid multi-layer elements showed an average of 2,3% of variation in the value of the tensile strength in relation to the tensile tests, regardless of the manufacturing process used.
