Developing a Design Process for Durability

Content: The seminar works through the 5 crucial steps for developing a design process for durability. Working from elastic finite element models, the five steps are:

• The calculation of elastic-plastic stresses and strains for complex loading and biaxial stress states
• Modification of the endurance limit to allow for the interaction between small and larger cycles
• The calculation of the life to crack initiation
• Critical plane searching to determine the orientation of a potential crack
• An assessment of whether the crack will propagate to failure

A technology update in key areas of fatigue analysis is provided:

• Multiaxial fatigue, effects of temperature, notch sensitivity and residual stresses
• Why traditional methods of metal fatigue analysis get it wrong
• An introduction to modern methods of metal fatigue analysis and why they get it right
• An introduction to using fe-safe™ with FEA software
• An introduction to Verity® in fe-safe™ for fatigue of welded joints including spot welds
• An introduction to fe-safe/Composites™ for fatigue of composite materials; fe-safe/True-Load™ for accurate in-situ load calculation and fe-safe/Rubber™ for fatigue of elastomers.

fe-safe™ - the technically advanced fatigue analysis software for FEA models. fe-safe™ incorporates the most sophisticated fatigue analysis technology available in commercial software. As a result, fe-safe™ is changing the way design engineers perceive fatigue analysis software tools. John Draper will provide a technology update on modern methods of metal fatigue and a demo of fe-safe™.

Who should attend: Design and Test Engineers responsible for product durability in the ground vehicle, aerospace and manufacturing industries interested in durability analysis. No previous knowledge of fatigue is necessary.
