Finite element analysis of static loading in donkey hoof wall.

This research article focuses on creating a computer model of a donkey’s hoof to investigate its responses to static load. The study aims to increase our understanding of the functional relationship between the hoof’s structural design and material properties.

Finite Element Model Construction

• The researchers built a finite element model of a donkey’s hoof using measurements taken directly from the left forefoot hoof capsule. This model forms the basis of their experimental testing.
• The model was designed with a 2mm mesh and consisted of 11,608 nodes. The use of a mesh structure was crucial for the application of the finite element method that they employed for the linear elastic analysis.

Simulation of Load Application

• The study assumes isotropic material properties in response to a 375-newton load to simulate static loading. In other words, the researchers applied a fixed weight on the model to analyse the hoof’s response.
• The weight was distributed by 400 laminae to simulate the real-life distribution of the pedal bone within the donkey’s hoof capsule. This is important in establishing a realistic strain on the hoof.

Assessment of Responses

• The research analysed various responses to the applied weight, including displacement of the hoof wall, stress concentration, the change in shape of an object, principal strain, and force distribution across the hoof wall.
• The findings revealed that the hoof wall’s reactions were generally in agreement with previous live animal studies and simulated observations of hoofs from similar animals.

Potential Implications of the Research

• The study indicates that finite element analysis has the potential to replicate hoof wall function at both macroscopic and microscopic levels. This can contribute significantly to the understanding of how hoof structure and material properties functionally interrelate.
• With more research in this area, it could be possible to discover how different structural organisations and materials in the hoof wall affect the overall strength and durability of the hoof and help in improving hoof care and disease management strategies.
