Polymers can be utilized for a wide variety of applications since they are lightweight and inexpensive, and their mechanical qualities are usually more than enough. Polymers often undergo a petrochemical production process and have a relatively lengthy elimination time. Green chemistry and green production are crucial in today's technology, which relies increasingly on non-toxic polymers made from natural ingredients. Biopolymers are a type of organic polymer that can break down naturally and pose no threat to human health or the environment. Here, we will take a quick look at the polymer structures that go into making eco-friendly composites in the future. Important polymer types and engineering studies for material manufacturing have been uncovered as a means of avoiding green production's negative effects on the environment. Possible future use of biopolymers as binders in composite materials and their effects on the environment.

“…It is necessary to combine surface damage with the stress state of the component under examination. The finite element method (FEM) becomes a valuable tool for forecasting this type of failure [13][14][15][16]. Among the various quantitative indexes for identifying fretting fatigue, the Ruiz parameter (Equation ( 1)) has been chosen as the selected approach because it can provide valuable insights into the tribological behavior of the components [17]:…”

Fretting fatigue is a well-known and dangerous damage mode that occurs on the mating surfaces of mechanical components, mainly promoted by a combination of stress distribution, contact pressure distribution, and relative sliding (micro)motion between the surfaces. However, predicting this mechanism is challenging, necessitating specific studies for each assembly due to variable influences. This article presents a methodology for evaluating fretting fatigue damage at the contact between a titanium connecting rod big end and the bearing, adopting the Ruiz parameter as a quantifying damage index. For this purpose, a thermal-structural finite element model is prepared. In particular, the machining and assembly of the split conrod big end are simulated, considering thermal effects. A full engine cycle is first simulated, and results are used for identifying critical instants to be considered for accurate yet computationally efficient calculations. The dependence of fretting fatigue on three factors is studied: bearing crush, bolts tightening torque, and friction coefficient between the big end and the bearing. In summary, the damage increases with a higher crush and friction, while tightening torque has marginal effects. Following a 20% increase in crush height, a corresponding 10% rise in the Ruiz parameter is observed. Conversely, reducing the crush height by 20% leads to an approximately 8% decrease in the Ruiz parameter. When the influence of the bolt preload is taken into account, only a marginal 1% increase of the Ruiz parameter is recorded despite a 30% rise in preload. Evaluating the impact of the friction coefficient on the Ruiz parameter reveals an almost linear relationship. These findings suggest that adjusting the screw preload can enhance the hydrodynamic behavior of the bearing without exacerbating fretting. Furthermore, exploiting the linear correlation between Ruiz and the friction coefficient allows for the generalization of results obtained with specific coefficient values. This methodology can, therefore, serve as a valuable reference for adjusting different variables during the initial design phases of a four-stroke internal combustion engine’s dismountable connecting rod.

“…Several components of mechanical systems are subject to high stress-strain concentration at contact interfaces, such as wheel-rail contacts [1][2][3][4][5][6][7], contact engagement between gear teeth [8][9][10], or rolling elements [11,12]. One of the ever-present examples concerns rolling bearings, in which the mechanical elements withstand different kinds of loads and kinematics.…”

When dealing with joints and bearings, high pressures localised at the contact interface lead to residual plastic strain. The present paper combines numerical simulations and experimental tests to investigate the role of the material constitutive law in the indentation process. Numerical indentation tests between similar materials showed a good agreement with the experiments when classical material laws recovered from tensile-compressive tests on bulk samples were accounted for. On the other hand, when simulating indentation between different materials in contact, the comparison between the numerical and experimental results highlighted the limits of using classical material laws. Bilinear material laws were then derived for different steel materials (ASP 2060 PM, 100Cr6, 440C, Marval X12, and Z15 CN17-03) in contact with a ceramic indenter, leading to the correct simulation of the residual indentation profiles (error less than 5%). The proposed approach to determine suitable material laws for indentation between dissimilar materials can be further applied when dealing with applications involving contacts undergoing local plastic deformation.
