Predicting Fatigue Failure to Increase Operational Availability
June 12 - 12:00 US Eastern
As we enter an era of reducing new equipment procurement coupled with a constrained spending environment, the sustainment community is under significant pressure to increase the life and operational availability of existing and aging assets with a flat or reduced budget.
In these circumstances, repairing equipment or replacing components on a fixed schedule irrespective of condition or exposure history introduces unnecessary costs and down time. Advanced fatigue modeling coupled with physics based simulation is a proven way to predict the remaining life of equipment and components and drive toward optimized condition based maintenance.
In this Webinar we will review the trends and pressures facing the engineering sustainment community and discuss in detail the ANSYS nCode DesignLife solution for finite-element based life prediction.

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.

Load Reconstruction in nCode DesignLife
With the release of nCode 9.0, a new capability has been introduced in DesignLife to calculate input loads using a set of physical strain gauge measurements together with the results of a unit load FEA using DesignLife’s Virtual Strain Gauge capability. The Virtual Strain Gauge feature in nCode DesignLife recovers the strains on an FE model resulting from the unit loads. These virtual gauges are positioned on the model to simulate the actual physical strain gauges. The overall method enables the component to act as a load transducer.
This webinar will outline the procedure for using load reconstruction to predict the input loads on a component during operation, starting with assigning virtual strain gauges to the model. Guidelines on the number of strain gauges and their placement will also be discussed.

Fatigue of Composite Materials
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.

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.

Originally presented: April 21, 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.

Design Optimization & Robust Design for Fatigue
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.

Model Fatigue of Engineered Polymers with DesignLife
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).

Fatigue Analysis - General Topics
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.

Introduction to Fatigue Analysis Theory
Fatigue analysis is an important aspect of component design. Typical yield stress design criteria miss the fatigue cycles seen in actual service use and hence can lead to improper design.
This webinar will provide a brief introduction to what fatigue means, what drives fatigue failures, and common methods of durability analysis. This is a great introduction for engineers tasked with validating a design against fatigue criteria, or anyone who wishes to learn more about the engineering practice of fatigue analysis.
