Analysis of FGM Beam by FEM Method Applying Abacus Software
Low–velocity foreign object impact damage is one of the most important issues in composite materials used in military and civil structures. Fiber composites are strong sheets, which are subjected to impact loads, to reduce the damage of the impact using hard resins. In this research, low-speed bullet impact to six beams with FGM layering whose modulus of elasticity in the beam thickness varies from ceramic to metal and the response of the beams to low velocity impact has been investigated by finite element method using Abacus software. The strain, displacement and tension of the beam have been analyzed in two modes of the last layer of the metal and ceramic – metal. A comparison of displacement, tension and strain diagrams along the length of the beam for the six beams has been made. It was observed that the higher the properties of the metal than the ceramic, the higher the amount of displacement and tension and the strain in the beam decreased with increasing degree of ceramic properties compared to the metal.
