“…The addition of TiB 2 particles increases the tensile strength of the composite as shown in Figure 9. This enhancement in tensile strength is attributed to increased percentage of TiB 2 particles in the Al6061 alloy and interaction between dislocations and TiB 2 particles when the composites bear a load 4 . The effect of the distribution of the TiB 2 particle on the elasticity is endorsed to the plastic deformation of the matrix 21 .…”

“…Some of the reinforcements available in the market are Alumina (Al 2 O 3 ), Silicon carbide, Boron Carbide (B 4 C), Titanium Di-Boride (TiB 2 ), Titanium Carbide 3 (TiC) etc. Out of which TiB 2 shows better properties in comparison with TiC and B 4 C. TiB 2 possess properties like High hardness at extreme temperature, better elastic modulus, higher toughness, higher compressive strength and excellent temperature resistance 4 . Hence from the literature and present study, it can be said that, inclusion of TiB 2 into the matrix improves the characteristics of the composite eminently 5 .…”

Synthesized Al6061-TiB2 composite material by varying wt.% of TiB2 through In-situ process by adding 1.5% Mg to evaluate mechanical properties. It is noticed that the tensile, impact strength and hardness of the composites increases with increase in wt.% of TiB2 with reduces in ductility. Microstructure analyses were conducted through SEM to observe the distribution, presence and formation TiB2 particles and found that particles were homogeneously distributed and EDX analysis confirms the presence of TiB2. Later, SEM images are converted into 2-D models using Matlab, FE analysis was conducted using ANSYS software to evaluate the stress at the matrix and reinforcement interface. The information revealed from this study is useful in design and selection of Al 6061-TiB2 AMCs for various applications.

“…The usage of numerical software has the distinct benefit of providing a distinct advantage, which is that the benefits and drawbacks of each model may be determined prior to the creation of the final items. The prediction of the stress concentration areas has been accomplished using ANSYS [23], while the generally employed numerical software programs to predict fatigue life theoretically and/or in comparison with experimental results are illustrated in Table 1. intensity range (K) relationships as inputs [30].…”

A significant number of high-performance engineering structures are repeatedly subjected to both thermal and mechanical loads, often in a combined fashion. However, because of the increase in the plasticity of metallic structures when they are loaded at high temperatures, the analysis become very complex. This presents a significant obstacle for the comprehension of both the growth of cracks and the thermo-mechanical fatigue performance of the material. Thermomechanical fatigue and thermal fatigue are characterized by external and internal constraining forces, respectively. The beginning and spread of thermal fatigue cracks are controlled by a variety of factors, including the modes of heating and cooling, the temperature range, the maximum temperature rates, and the holding times. The process of a crack beginning and the rate at which it spreads are both sped up when the temperature is raised. However, because of the development of powerful statistical learning algorithms as well as rapid advancements in computational power, there has been an increased adoption of machine learning approaches as well as other advanced computational analyses and numerical software for crack damage detection and damage severity. This has led to an increase in the use of these methods.

“…However, very limited information is available on the material properties of the coating. Although some relevant data of coated aluminum alloys are available [128][129][130][131], direct applications of existing properties should be practiced with caution because material properties of coating depend on the coating process and the constitution of coating materials. In case the coating is required to be treated separately in the finite element model, a subroutine algorithm to reference the material properties that includes the S-N curve must be available.…”

Actuators are essential components for motion in machines, and warranty service lives are basic specifications of actuators. However, fatigue damage or wear of actuators are very complex and related to many design factors, such as materials properties, surface conditions, loads, and operating temperature. Actuator manufacturers still rely heavily on physical experiments to determine the fatigue lives of actuators. This paper investigates the state-of-the-art of using numerical simulations for fatigue analysis of mechanical actuators. Failure criteria of machine elements are discussed extensively; existing works on using finite element methods for machine element designs are examined to (1) explore the feasibility of using a numerical simulation for fatigue analysis and (2) discuss the technical challenges in practice. Moreover, a systematic procedure is suggested to predict fatigue lives of mechanical actuators with Teflon impregnated hard coatings. A virtual fatigue analysis allows for optimizing a mechanical structure, reducing design verification costs, and shortening the development time of actuators.
