“…Because of the uncertainty associated with the design parameters, the goal is to determine the parameter values u 1 , u 2 , u 3 , u 4 , u 5 , t 1 , t 2 , t 3 , t 4 , and t 5 , so that the probability of successfully performing product functionality is maximized. 12,13 Let the maximum displacement of X 6 be expressed as d max . Owing to the linearity of equation (6), the mean and variance of d max can be predicted by equations (7) and (9), respectively.…”

“…Assume that y max and d max represent a probabilistic normal distribution with mean values and standard deviations, as shown in equations (7)-(10). 14 Clearly, y also behaves as a normal distribution with mean values and standard deviations, as revealed in equations (12) and (13). 15 Because of uncertainty, Figure 4 represents the probability that the product performs its functionality well under the linear elastic displacement without permanent deformation.…”

In regard to the parameter and tolerance design of an assembly, a previous assumption has been that the structure of an assembly is not subject to any geometrical deformation under application. However, the realized deformation of the structure may well have an impact on the appropriate performance of the assembly. The impact may become even greater when the geometric magnitudes are distributed over an uncertain range. The magnitudes of structure geometry can be represented by the associated parameter and tolerance values. In this regard, this study aims to have the optimal parameter and tolerance design determined all together under the impact of structure deformation through a probabilistic method and mathematical programming formulation. An example of an assembly with mechanical loading for uncertain magnitudes of geometry is chosen for demonstrating the proposed approach.

“…FGMs are advanced composite materials that can be tailored in such a way that the properties, microstructures, porosity, phases, and composition varies across the volume of a product from one region to another [12][13][14]. The main difference between traditional composites and FGMs is the distribution of reinforcement particles.…”

This paper delivers a detailed review of the influence of material and process variables on the microstructure, mechanical and tribological characteristics of functionally graded aluminum matrix composites (FGAMCs) produced by the ex-situ centrifugal casting method from previous studies. Also, the basic principle and classification of centrifugal casting to produce FGAMCs are illustrated. The ceramic reinforcement particles are classified based upon their uses in the processing of FGAMCs through the ex-situ centrifugal casting technique. In addition, using the linear regression model, an effort has been made to optimize the material and process variables to get enhance the mechanical properties. It is seen from the optimization while mold preheating temperature ranges 250–350 °C, centrifugal speed kept between 600 and 1300 rpm, pouring temperature in the range of 740–760 °C having reinforcement particle of 10–15 wt%, with an average particle size of 18–50 µm yield the maximum of hardness and tensile strength. This paper aims to provide direction to future researchers to develop advanced material using this route and thus, to boost technological growth.

“…A large body of research on FGM kinds has been extensively conducted in different subjects such as Vibration analysis [1][2][3][4] and thermal analysis. [5][6][7][8][9] However, more attention has been paid to the mechanical analysis of functionally graded piezoelectric materials. [10][11][12] In addition to mentioned research fields on FGMs, elastic waves in FGMs were explored in some studies related to the propagation and identification.…”

The goal of this research is to numerically look for a proper feature for functionally graded materials mechanical property distribution function evaluation based on through transmitted ultrasonic bulk wave amplitude variation. A numerical approximation called homogenous layers approximation is introduced and employed for wave propagation formulation in functionally graded plate, followed by finite element utilization for verification. As the amplitude of the propagated ultrasonic wave is affected by acoustic impedance and wave divergence angle variation in the functionally graded material plate thickness, while neglecting the attenuation phenomenon, numerical investigation has been performed in order to quantify the contribution of each mechanism on the wave amplitude behavior. One-dimensional investigations, using homogenous layers approximation and finite element method, show that the final value of the wave amplitude is the same for all functionally graded material property distribution function power index, while two-dimensional results, obtained from finite element method, provide a suitable amplitude variation manner based on the wave divergence angle variation in functionally graded material thickness direction. The final results shows that it is possible to calibrate the received wave amplitude distribution on the receiving side of the plate, in a through transmission test, for the material property distribution function power index evaluation. Moreover, the concept of functionally graded material ultrasonic shoe is introduced, suitable for beam focusing applications instead of expensive phased array systems.
