Ensure product integrity by designing for durability with ANSYS fatigue software. Understanding if and when a product can fail reduces product — and organizational — risk and cost. The ultra-competitive nature of today's economy has steered product development organizations to reduce costs, improve time to market, build in innovation and design for sustainability. And now there's a new push: prolonging product life and ensuring durability. Recent headlines highlight the massive costs of product recalls, warranties, environmental remediation and regulatory penalties. But these pale compared to the impact on corporate brand image and consumer confidence. 1 As a result, making informed design decisions to improve your product's durability is increasingly important. Product failure can result in recalls, high repair costs, legal liabilities, and damaged brand and corporate reputations. Designs that are too conservative are costly to manufacture, and they may not be competitive. On the other hand, designs that are not conservative enough may fail under normal — let alone unanticipated — usage. Reaching the right product integrity balance is critical to your success. Fatigue is a major source of product failure. Most products exposed to repeated cyclic loadings will eventually fail. Caused by repeated or otherwise varying loads, fatigue is a result of repetitive stress over time, as microscopic changes become cracks that cause malfunction. Optimizing a product's shape, size and material via simulation is the most cost-effective way to arrive at the desired product life. Beyond Structural Mechanics Analysis Engineers design today's products using structural mechanics solutions that compute the response to applied forces and displacements. Fatigue simulation expands on structural analysis to account for extended real-life loadings. To determine when failure will occur, you can use the Fatigue in gear Multi-axial stress loading history
