Reliability Design of Pressurized Structural
Devices Under Cycling Load
High-volume manufacturers of consumer
items and low-volume producers have the same goal: to bring a product to
market using a process focused on designing out or mitigating potential
failure modes prior to production. For this activity, the reliability
team performs three fundamental activities: Design for Reliability,
Reliability Verification and Analytical Physics. Complexity arises
when high non-linear geometry or loading makes it difficult to model
a system even using available state-of-the-art finite element software
or analytical techniques. There have been continuing efforts in developing
analytical techniques for those who are responsible for product reliability
and product design. Techniques for data acquisition, analysis, test planning
and practice with combining reliability techniques using fatigue theory
concepts can be a systematic approach to the design process. In this
presentation we will discuss the development phase through the application
of Design of Experiments techniques, Accelerated Life Testing and Monte Carlo
simulation for the design of pressurized flexible structural elements for
different types of stress levels.
