They are made of two or more distinctive and immiscible materials with different mechanical, physical and/or chemical properties.

To supply these needs, composite materials were developed. Technological advancements have led to an increase in the demand of special materials with unique properties that cannot be found in metal alloys, ceramics or polymers blends. In addition, the present article lists the main industrial sectors in which composite material simulation is used, and their gains from it, including aeronautics, aerospace, automotive, naval, energy, civil, sports, manufacturing and even electronics. The text also discusses the types of elements most commonly used to simulate composites, which are solids, peel, plate and cohesive, as well as the various failure criteria developed and used for the simulation of these materials. Regarding properties, different mechanical characteristics, theories and constitutive relationships involved to model these materials are presented. From the modeling point of view, different levels of modeling-micro, meso and macro, are presented. Therefore, this work aims to approach the modeling of composite materials, focusing on material properties, failure criteria, types of elements and main application sectors. As a result, the finite element method has been used as a way to analyze composite materials subjected to the most distinctive situations. However, due to their high costs, as well as unique characteristics, consequences of their heterogeneity, they present challenging gaps to be studied. The use of composite materials in several sectors, such as aeronautics and automotive, has been gaining distinction in recent years.
