Investigation on linear Fraction behavior of Composite Beam

This paper Deflections of linear two-material composite beams with rectangular cross-sections and singular force acting from the free endpoint were investigated in this study. Large displacements in carrier systems that occur under various loads are a well-known topic, and numerous studies have been undertaken on the subject. Materials have a stress amplitude(s) value; at stress amplitude values below this value, fatigue is not possible even if the material is subjected to an infinite number of stress cycles. When a material is continuously subjected to periodic stress, depending on the magnitude of the stress and the time subjected to stress, the material will fracture even if the applied stress is below the maximum tensile strength of the material. This is called fatigue. Each material has a limit of resistance to fatigue until it changes from elastic deformation to plastic deformation. The equations the result is based on are a dimensionless parameter that can be written using the load, beam length, material cross-sections, and elasticity modulus. Studies on this topic are still ongoing today due to the relevance of the subject. The answers achieved by linearization can be adequately approximated in many circumstances encountered in various engineering domains. As a result, displacements may rarely be estimated using analytical methods, necessitating the employment of approximate and numerical approaches. Huge displacements in linear elastic cantilever beams with uniform and non-uniform, singular, and radiated charges have been studied extensively.
