Aerospace structures and increasingly other applications such as heavy equipment typically need to tolerate the presence of cracks during real-world operation. The challenge is to optimize inspection intervals and to ensure cracks are detectable prior to catastrophic failure.

This webinar provides examples of damage tolerant design using Crack Growth capabilities in nCode software. Topics covered will include:

• Predicting critical crack lengths, growth rates and estimating maximum permissible flaw sizes
• Performing forensic failure studies including estimation of initial flaw size
• Crack Growth being now included as part of GlyphWorks Fatigue and DesignLife products.

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.

A shaker table test can prove the durability of a component that sees vibration loading. But how do you create the shaker profile? How do you compare this to an existing test spec?

Join us as we discuss:

• Defining an equivalent damage shaker test for random or swept sine vibration testing.
• Accelerating this shaker test to save test time.
• Verifying that the accelerated test is still reasonable in terms of shock.
• Comparing different shaker test specifications - which is more severe?
• Comparing measured vibration data with an existing test specification - how conservative is the existing vibration profile?

Utilizing wind turbines for electric power generation depends on the structural integrity of the equipment operating continuously over long periods of time. This 45 minute webinar demonstrates how nCode software is used by turbine designers and operators to:

• Predict fatigue damage in design of key components such as gearboxes
• Understand the structural loading envelope
• Monitor operational performance and identify statistical trends
• Assess the reliability and structural integrity of the systems for long term operation

Fatigue is an important design consideration for modern wind turbines. In this webinar we describe how fatigue failure locations and fatigue life estimates can be obtained using Finite Element-based stress analysis. Guidance is given on selecting appropriate material parameters and load spectra, along with advice on how to optimize the analysis for faster preliminary design assessments.

An overview of the theory is also presented for those who are new to FE-based fatigue analysis.

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.

nCode DesignLife is an industry-standard software package for fatigue life prediction of engineering components and structures. It now has a Python-based customization capability which allows organizations to rapidly deploy new or proprietary fatigue analysis methods.

The majority of metal fatigue life predictions reasonably make the assumption that material properties are homogeneous and isotropic. These assumptions are quite inappropriate for predicting the life of fiber reinforced plastics, the fatigue strength of which is strongly dependent on fibre orientation and density.

During this webinar we will demonstrate the Python-based customization capability in nCode DesignLife, implementing as an example a method for predicting the life of components made from engineered polymers (plastic matrix with short fibers).

This webinar demonstrates the use of nCode DesignLife with commercial process integration and design optimization software. In this example, we use DesignLife together with modeFRONTIER. You will see procedures that can modify the DesignLife process properties, run that process in batch, and capture key results.

To illustrate this, nCode DesignLife is shown as a part of two modeFRONTIER workflows. The first workflow performs a stochastic fatigue analysis, assuming several of the DesignLife inputs are statistical distributions rather than fixed constants, where the resulting output is a distribution of predicted life. The second example includes DesignLife in a workflow performing multi-objective shape optimization, where fatigue life is one of the constraints on the design space.

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!
