Numerical Study of the Mechanical Behavior of a Composite Material Plate

Abstract

Composite materials are playing an increasingly significant role in the field of mechanics, such as aeronautics, aerospace, ships, and modern cars. The objective of this work was to investigate the mechanical properties and behavior of a composite plate (carbon/epoxy) through various tests, including tension, compression, and bending, using numerical analysis. Additionally, static analysis of mechanical behavior was performed, as well as the natural vibration of undamped structures. This analysis aimed to determine stresses, displacements, natural frequencies, and modes of free vibration. The obtained results illustrated that the composite material has a significant impact on improving the quality of mechanical properties and increasing the lifetime of materials, making it a valuable option for design and repair techniques. Furthermore, the results obtained in this work align well with previous literature studies. By examining these parameters, this study aimed to enhance our understanding of how composite materials perform under different mechanical loads and dynamic conditions, thus contributing valuable data to advance the field of composite mechanics.
