An important input to durability analysis is service loading: How does a customer actually use the product you are designing? and, how can your durability analysis best reflect these loads?

In this webinar, we will explore how signal processing tools can be used to accurately define input loads for FE-based durability analysis with nCode DesignLife. Demonstrations will also show how these signal processing tools – frequency spectra, statistical analysis, cycle counting, etc. – improve understanding of service loading.

Engine- or gear box-mounted components are submitted to loads coming from both the rotating machinery and the road profile. This vibratory mechanical environment is traditionally defined as swept sines or random profiles. In this webinar, we will present a methodology which enables to you to superimpose swept sines and a power spectral density of acceleration to optimize and accelerate the durability tests of such components.

Proving grounds are an extremely efficient means of qualifying the durability of vehicle components. They accelerate damage accumulation rates so failures are detectable in a very short period of time. It is important that proving ground damage is correlated with target customer usage. It is also important to determine the most efficient use of the proving ground in order to meet project targets and minimize overall development costs. This webinar describes the latest techniques for proving ground correlation and optimization that will be available in the next release of nCode GlyphWorks.

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!

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.

The fatigue of composites poses particular challenges for engineers because of the properties of the constituent parts (polymer matrix and fibers) interact to determine the fatigue properties which vary in each location and direction. Fatigue analysis requires the combination of various inputs including material modeling, finite element analysis and fatigue characterization of the material based on fiber-share and orientation. This webinar gives an introduction to these topics and gives a preview of the fatigue life prediction of short-fiber composites introduced in nCode DesignLife 8.

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.

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.

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.

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).
