Worked examples for high-cycle fatigue strength assessment

Introduction

NAFEMS wishes to commission an author to the on-demand course “Worked examples for high-cycle fatigue strength assessment”. The assessment of fatigue strength is a challenging task, involving complex simulation, post-processing, and calculation steps. This course is expected to deliver guidance to analysis engineers on the necessary steps and underlying theory to derive results useful for the design against high-cycle fatigue.

Intended Readership

The intended readership consists of simulation engineers involved with structural FEA.

Contents

The course is expected to provide a practical guide, with links to underlying theory for analysts, including (but not limited to) the following topics;

• application of academically and industrially established methodologies without relying too much on specific guidelines (e.g., FKM) and standards (DNV GL, ASME BPVC) to provide a general understanding of the assessment,
• at least 4 example problems for metallic materials (using any major FE-code, and a tool such as Microsoft Excel or SMath for calculations),
• the problems should represent a balanced coverage of the following areas: high-cycle fatigue, welded fatigue strength, mean stress effect, multiaxial fatigue, local (e.g., notches) and structural (e.g., tension vs. bending) stress gradients, surface conditions.

Format

The on-demand course is aimed to be delivered through the NAFEMS Learning Hub, consisting of text, formulas, figures, videos, quizzes, and downloadable files. Further specification and support will both be provided by the NAFEMS technical and marketing teams. The approximate learning time of the total course for course attendees is expected to be around 3 to 5 hours.

Cost

The total cost is not expected to exceed £6000 (GBP), and it is expected that the course will be completed within 12 months from NAFEMS approval.

Guidance for Proposals

Each proposal should consist of:

• the proposed structure of the course with specification of the individual examples,
• work plan including milestones and interim deliveries for early review,
• cost,
• The authors' credentials, curriculum vitae, etc. (Proposals from single authors and consortia will be considered.),
• The PSE competencies that the publication is anticipated to address. The PSE competencies that the publication is anticipated to address. Review the list of PSE competencies for “Fatigue”. Contact technical@nafems.org to obtain access.

Submission

All proposals should be sent to NAFEMS at technical@nafems.org to arrive no later than 1st of January 2025.
