FEA (Finite Element Analysis) uses computer programming to test how prototypes for new products, including mining equipment, will perform in real life – including predicting their fatigue life.
Product design engineers like us at E3K Australia offer FEA consulting services to complete mining machinery failure analysis. Mining companies want their machinery to be up to date, long-lasting, and efficient. Our role is to extend the lifespan and boost the functionality of products to benefit the mining industry. So, in this blog post, we’ll help define FEA and its role in Fatigue Life Prediction in mining machinery.
Why FEA and Mining Equipment Fatigue Life Prediction?
- An FEA engineer saves companies time and money by removing the need to create physical prototypes.
- Without proper prototyping, equipment can fail. This slows down work and, due to the need for more manual effort, lowers morale in staff, creating reduced productivity.
- FEA instead allows prototypes, when eventually made, to be much closer to ready for the market. FEA is able to test the product, component, or machine for real-life stressors like heat, pressure, weight, and movement.
- It can even predict the lifespan of the product by testing its specific build and materials for longevity in the environment it will be performing in, just like its fatigue life.
Using Finite Element Analysis to Predict the Lifespan of Mining Equipment
What is Fatigue Life Prediction in Mining Equipment?
Mining equipment needs to be both functional for productivity and safe for use by the mine staff. If it were to fail, major issues could arise, like workflow blockages, major loss of profits, or even injuries.
‘Fatigue Life Prediction’ refers to the calculation of how many ‘cycles’ a piece of machinery can go through before it’s likely to fail. Any piece of machinery can only take so much stress, especially in a high-use, heavy-lifting environment like mining, before it succumbs to fatigue. Common mining machinery like bulldozers and excavators typically lasts above 10 years or 10,000 hours.
For mining companies, mining machinery failure analysis is important to consider in budgeting and planning workflow. If companies are able to predict when a piece of equipment will reach the end of its life, they can plan ahead.
How Can FEA Help With Fatigue Life Prediction in Mining Equipment?
FEA consulting services can provide industries with insights into the behaviour of machine parts, which in turn enables better equipment production. An FEA engineer is able to simulate real-life conditions for components and machinery, without needing to test in real life. It catches failure points, which enables the engineers to make recommendations to the company creating the product on how to extend the fatigue life. Being able to test components for longevity also means that better, longer-lasting machinery can be made. This can increase productivity, boost workflow, and save money for mining companies.
Making Mining Equipment Last Longer

Frequently Asked Questions
FEA works well for heavy machinery in high-stress environments, particularly equipment prone to fatigue. This could include excavation equipment, trucks, crushers, conveyers, drills, and more.
Yes, significantly. It reduces the costs associated with physical prototyping, prevents premature product failures, limits expensive over-engineering, and minimises the risk of costly warranty claims or product recalls.
Fatigue life is determined by the cyclic stresses and harsh working conditions associated with mining. This includes the frequent heavy loads, tough materials, high stress, and environmental conditions like high heat and humidity.
