Abstract

The process of damage and failure in composite materials constitutes a complex problem due tothe various failure modes acting and interacting within the material. Several damage and failuremodels have already been proposed in the literature, but this is still an open problem due to thenature of this type of material. Additionally, it is well known that the manufacturing processsignificantly influences the performance of composite materials, and one of the most importantparameters to be controlled is the amount of voids that result from a given manufacturing process.mention the printing of composite materials. Additionally, it is rare in the literature to find modelsof damage and failure of composite materials where the voids arising from the manufacturingprocess are considered. Therefore, this research project aims to investigate the influence of voidsin the process of damage and failure of composite materials and propose a new model of damageand failure for composite materials considering the influence of voids arising from 3D printingprocesses.
