Failure mechanisms refer to the processes or events that lead to the breakdown of materials or systems. These mechanisms can include factors such as fatigue, corrosion, and wear, which can weaken structures over time. Understanding these mechanisms is crucial in fields like engineering and materials science to prevent unexpected failures. Different materials exhibit various failure mechanisms based on their properties and environmental conditions. For instance, metals may experience fatigue due to repeated stress, while concrete can suffer from cracking due to temperature changes. Identifying these mechanisms helps in designing more durable and reliable products.
