Modelling and analysis of large-sliding geometry surfaces using finite element method

<ns3:p>The model is constructed to analyse an oil engine rubber gasket used in sealing the engine block against leakage. The basic goal of gasket design is to reach and withstand the maximum value of contact pressure at the block engine interfaces.The rubber gasket has a bead with two planes of symmetry, so it can provide a sealing effect as soon as it is compressed. In the present work, the commercially available finite element analysis software ABAQUS was used to model the process. To improve efficiency and reduce the need for trial-and-error methods, the finite element method can be used to model each forming process stage computationally.As a result, the obtained deflection-load curve is considered an indication of the required load to attain a certain gap and clearance between the engine block and the oil rubber gasket. The clearance value of (0.41 mm) between the upper forming surface and the lower deformed surface was estimated as a maximum value. In such a forming type, this value is considered adequate and acceptable. Also, the analysis results confirm that strains and stresses are within an acceptable range during the maximum forming load. It also concluded that a good agreement between displacement and load during the contact of the rigid surface with the rubber gasket.The main limitation of the types of material is that the loss of flexibility can result in a significant reduction in the effectiveness of the sealing ability, as the gasket may not conform to the mating surfaces it was designed to seal, thus resulting in leaks. Future research on rubber gaskets may explore several areas, including the effects of temperature and stress on seal performance, as well as materials that can improve durability and performance. Additionally, there may be a focus on developing gaskets specifically for fuel cell applications, a growing industry segment.In recent years, there has been an increasing demand for more efficient processes to form a linear elastic material, such as rubber and some elastomer types. Forming has emerged as a potential solution due to its ability to produce parts with good mechanical properties and surface finish. Parts and components, such as rubber products that change their shape during deformation, can fold substantially, allowing different surfaces of the parts to come into contact with each other. However, it is difficult to predict where the onset of such contact may occur in these cases. Consequently, the independent surfaces are also difficult to define during this contact. The modelling and analysis process illustrates the capability of single-surface contact in large-sliding two-dimensional geometry.The new contribution focuses on improving methodologies to simulate and analyse how these surfaces behave under different conditions, including large slip scenarios, which may affect wear properties and performance.The value of this paper is important for researchers and professionals in fields such as materials science, mechanical engineering, and nanotechnology, as it provides insights into surface design and its effects on functionality and durability.</ns3:p>
