In a previous article I discussed the degradation of materials due to exposure to stressors (use conditions) and how to identify stressors. Cracks form and grow in axles and shafts due to cyclic stress, steel screws corrode when exposed to water, some plastics become brittle when exposed to sunlight, and coatings on surfaces can wear away. When too much degradation occurs, components and joints fail, leading to product failure.
Things to consider during design
If you’re someone who likes to design reliable products, you must think about the stressors and their effects. When designing a product, we must identify the following things [Read more…]
