Abstract
The effect of erosion on the economy is widely acknowledged, with solid particle erosion (SPE) being recognized as one of the most significant forms of erosion resulting from the collision of solid particles with materials. While studying and comprehending erosion can be challenging, researchers have dedicated their efforts to this field and have devised models to anticipate the erosion rate of material elimination from the surface of an object, based on the material's response to solid particle impact. Most erosion models for composite materials take into account various physical and mechanical properties of the material, such as its density, porosity, modulus, strength, and fracture toughness. They also examine the characteristics of the particles that cause erosion, such as their size, shape, and hardness. Erosion models for composite materials are used to study the impact of different factors on erosion, such as the effect of particle size, velocity, and impingement angle. They are also used to optimize the design of composite materials and structures for specific applications and to evaluate the performance of protective coatings and erosion-resistant materials. Erosion models for composite materials can be either empirical or process-based. Empirical models use statistical relationships to predict erosion rates based on observed data, such as the size and shape of the particles, the velocity of the impacting particles, and the impingement angle. While the process-based models, on the other hand, use mathematical equations to simulate the physical processes that drive erosion, such as the deformation and fracture behaviour of the composite material under impact loading. Overall, erosion models for composite materials provide a valuable tool for understanding and predicting the complex processes that drive the erosion of composite materials, and for developing effective strategies to mitigate its impact on their performance and durability in various applications.
