ME57100 - Reliability-Based DesignSpring 2016
Days/Time: TBA / TBA
Credit Hours: 3
Enables students to understand the importance of reliability and quality in the design and manufacture of engineered products, components and systems. The methods of reliability analysis and reliability-based design of mechanical and electronic systems are presented with illustrative examples.
The course is aimed at providing an engineering view (as opposed to a purely statistical view or a management view) of reliability analysis as well as reliable product design. The goal is to make the student familiar with both the statistical tools as well as the failure physics that enable one to model time to failure of products and to use such models during design phase to ensure reliable product designs. The major topics that will be covered include: probability and random variables; normal, exponential and Weibull distributions and their manipulation; reliability estimation and plotting; acceleration factor modeling, Monte Carlo simulation; load-strength analysis, and Failure Modes Effects Criticality Analysis (FMECA); reliability of mechanical and electronic systems; selected failure mechanisms and time to failure modeling of mechanical and electronic systems.
Introduction; probability rules; probability examples; conditional probability; algebra of expectations and variance; normal, lognormal, exponential and Weibull distributions; failure rate modeling; binomial and Poisson distributions; reliability block diagrams; Monte Carlo simulation; uncertainty in load and in geometry; first-order reliability methods; load strength interference; time to failure modeling for selected failure mechanisms in mechanical and electrical systems.

ProEd minimum computer requirements; Require access to MATLAB and Excel. Require MATLAB Statistics Tool Box, which does not come standard with the student version of MATLAB. Off-campus access to full version of MATLAB is available through a web interface via Purdue ITaP's Software Remote service site (http://goremote.ics.purdue.edu). As with the course webpage, Purdue login is needed to access the the remote software. A high speed internet connection is critical to use Purdue University computing servers to complete projects.
