“…14 Multiple analytical studies in the energy and nuclear sector were carried out on parts like T-junction pipes, conical shells, and turbomachinery blades. [108][109][110][111][112][113] There has been a spike in FGM usage in biomedical applications in the past few years because of its ability to provide excellent biocompatibility. Table 2 shows the overview of the application in different areas.…”

Functionally graded materials (FGMs) are specially designed composite materials that gradually change their material properties. This distinctive property of materials comes with new challenges in the design and manufacturing sector. For such challenges, the best options are material property computation and material modelling using different computational materials science (CMS) algorithms. This review paper provides enriched information on CMS with an overview of the available FGM production techniques with a detailed study of FGM use in biomedical applications based on the available literature over the past couple of decades.

In the present work, low-velocity impact behavior of pre-twisted carbon nanotubes (CNTs) reinforced functionally graded (FG) sandwich conical shell panels is studied using finite element method. The top and bottom face sheets are reinforced with single-walled CNTs reinforced FG materials with various patterns. The temperature-dependent material properties of the CNTs reinforced functionally graded facings are evaluated using micromechanical models. The dynamic equilibrium equation of the impacted sandwich panel is formulated using Lagrange’s equation. A modified Hertzian contact law is used to evaluate contact force. The solutions of the resulting equations are obtained using Newmark’s time integration method. After validation study of the present method, the effects of the CNTs grading pattern, velocity of the impactor, size of the impactor, CNTs volume fraction, operating temperature, angle of twist, and core-to-facing thickness ratio on the low-velocity impact response of the CNTs reinforced functionally graded sandwich conical shell panel are studied in detail. Numerical results show that increasing the volume fraction of CNTs increases the contact force while a lower contact force is predicted at elevated temperatures.

“…The authors also included the modified indentation law in the FE formulation to evaluate the impact-induced contact force. Das et al 69,70 examined the dynamic behavior of perfect and porous FGM conical shells subjected to impact loading using FEM. The FE formulation was developed on the basis of the kinematics condition of FSDT to model the pre-twisted conical shell.…”

A finite element method-based dynamic analysis of pre-twisted sandwich conical shell panel having functionally graded graphene-reinforced composite (FG-GRC) facings and homogenous core without or with pores under low-velocity impact in thermal environments is performed utilizing a higher-order shear deformation theory (HSDT). In each facing, the graphene sheets are either uniformly dispersed or layer-wise functionally graded across its thickness. The extended Halpin-Tsai model is employed to estimate the temperature-dependent elastic properties of the nanocomposite facings. The contact force induced between the impactor and target panel is computed through the modified Hertzian contact law. The equations of motion of the FG-GRC sandwich conical shell panel are formulated based on Lagrange’s equation. The solutions of the resulting equations of motion are obtained employing Newmark’s time integration scheme. After verifying the consistency and accurateness of the present method, the effects of some critical parameters like graphene grading profile, temperature, core-to-facings thickness ratio, pre-twist angle, span-to-cone length ratio, impactor’s initial velocity, impactor’s size, and porosity coefficient on the impact response of the pre-twisted FG-GRC sandwich conical shell panel in uniform thermal environments are scrutinized.
