“…The modeling of FGM is important in the study of cylinders, pressure vessels, spheres, plates and disks (Abdalla et al , 2020; Madan et al , 2019c). A mismatch in experimental and theoretical results is owing to many reasons such as porosity, shrinkage, binding, geometrical factors (size, shape and orientation of fibers), environmental conditions and human error (Verma et al , 2019). With recent advances in fabrication techniques such as microwave sintering, a density of about 90%–93% of theoretical density can be achieved (Sinha et al , 2020).…”
