Making informed product design decisions to improve your product's durability is increasingly important in today’s highly competitive economic climate. Organizations are under pressure to reduce cost, decrease time to market and improve sustainability as well as push for longer product life. Product failure can result in recalls, high repair costs, legal liabilities and damage to a product brand. To be successful you need to reach the right balance in your product design. Designs that are too conservative are costly to manufacture and may not be competitive, while less conservative product designs may fail while in use.
Fatigue, a major source of product failure, can sometimes result in significant damage and injuries. When exposed to repeated cyclic loadings most products will eventually fail. Fatigue is caused by repeated or otherwise varying loads and only occurs from exposure to repetitive stress over time as microscopic changes become cracks that causes the malfunction. Breakdown of any product or part, even when not catastrophic, can result in hefty expenses. Optimizing the shape, size and materials employed by using simulation is the most cost-effective way to arrive at the desired product life.
