An Update on Materials Engineering & Selection
Materials engineering is developing at a rapid pace. New materials, which boast improved performance in many areas, are continually being introduced. At the same time, many traditional materials are being either changed or withdrawn through environmental legislation. Fatigue resistance is only one attribute of a material. As design engineers working in fatigue, it is important that we understand how fatigue performance is affected by changes in our materials. How do we specify fatigue performance? How do we know if a proposed material is a suitable replacement for an existing solution? Very often the understanding that led to those original solutions has been lost in time and we certainly do not want to reproduce errors of the past.
As a person with design responsibility you might consider the following point
- What questions should the materials specialist be asked?
- What data are needed to support the design?
- Can I guarantee the suitability of this material for fatigue?
This free webinar will provide a brief introduction to materials engineering and selection for new design engineers as well as offer a refresher course for senior engineers.

Overwhelmed by Data? Solutions for Making Key Decisions from your Test Data
Engineers are often overloaded with data and can waste much time looking for the data they require. Timely storage, retrieval, and usage of that data often limits the ability to get the right information to the right person, causing costly delays and/or wrong decisions to be made. All too commonly, the location and meaning of the data is really known only by the test engineer who measured it. Data from expensive physical tests can rapidly become worthless, and in some cases, complete tests may have to be repeated.
One part of the solution is to enable collaboration between the design, analysis, and test departments; another is to use web-based technology to automate data analysis efficiently. This webinar will highlight how large amounts of data are handled efficiently in nCode Automation, a collaborative, web-based environment for automated analysis and test data management.

Durability Assessment of Adhesive Bonds in Vehicles Bodies
This webinar describes a fracture mechanics-based approach for the durability assessment of adhesive (and hybrid) joints in vehicle bodies. The drive to reduce carbon emissions is motivating car and commercial vehicle manufacturers to develop increasingly lightweight vehicle bodies, usually constructed from high strength steels and aluminium alloys. In order to realize the potential strength and durability of such structures, adhesive bonding is commonly used, normally in conjunction with spot welds and self-piercing rivets. The method described here, and implemented in nCode DesignLife 8.0 as part of a 3.5 year research project, provides a CAE tool for evaluating the durability of adhesive and hybrid joints during the design/development process. This is essential if unnecessary overdesign and un-quantified safety factors are to be avoided.

Batch Processing in nCode DesignLife
This webinar gives practical instruction in setting up DesignLife for batch submission enabling design optimization and the solution of larger jobs on remote computers.
Originally presented: November 10, 2011
Many components and structures are subject to complex loads in service, which may result in fatigue damage. In some cases, although the applied loads are complex, the geometry and load paths create stress states locally that are relatively simple. In others, the relative size and/or phase of local stress components may vary with time, giving rise to multiaxial loadings. Multiaxial loadings require greater sophistication both in terms of modelling stress-strain response, and predicting fatigue damage.
This webinar shows how DesignLife may be used to understand multiaxial loadings, and looks at the methods available for analysis and automatic selection of appropriate criteria.

Customizing GlyphWorks using Python Scripting
Python scripting provides a very flexible and powerful method of adding new or proprietary functionality to nCode GlyphWorks. Some tasks require custom programming such as reading or writing new file formats or using a calculation that is specific to your company and this is where Python scripting has major benefits.
This webinar shows through several examples how the Scripting glyph can be used to rapidly create and implement your own glyphs.
Even if you have never used the Scripting glyph before, this webinar is a good place to start!

Helicopter - Shock & Vibration Qualification of Equipment
This webinar reviews the source of vibration loading on a helicopter and describes standard qualification tests that are used to ensure the safe life of equipment on the aircraft. It describes how the vibration environment can be measured in terms of a Fatigue Damage Spectrum (FDS) and Shock Response Spectrum (SRS). These spectra are calculated from measured flight load data as well as from the vibration test. By comparing the flight spectra with the test spectra, the paper shows how highly optimized vibration tests are derived.
Although the paper deals specifically with helicopters, these techniques are now common in all industries, including: ground vehicles, offshore, power generation and electronics.

Equivalent Damage Block Cycle Test with nCode GlyphWorks
Block cycle testing is a common method of component durability validation. It relies on the concept of equivalent fatigue damage to condense complicated service loads into a simple set of cycles that can be easily reproduced in the test lab.
Watch this webinar to learn how nCode GlyphWorks software can be used to easily create an equivalent damage block cycle test. We’ll discuss some of the common requirements of a block cycle test, and tips and tricks that can improve the accuracy of the test profile.
