Worked examples for cyclic plasticity and low-cycle fatigue strength assessment

Introduction

NAFEMS wishes to commission an author to the on-demand course “Worked examples for cyclic plasticity and low-cycle fatigue strength assessment”. This course is expected to deliver guidance to analysis engineers on the necessary steps when conducting analyses involving cyclic plasticity and low-cycle fatigue strength assessment.

Intended Readership

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

Contents

The publication 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 nonlinear) 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),
• inclusion of concepts such as cyclic hardening - softening, elastic shakedown, plastic shakedown, ratchetting and mean stress relaxation,
• the problems should represent a balanced coverage of the following areas: material model identification, simulation of cyclic plasticity, low-cycle fatigue analysis of a (simple) component.

Format

The on-demand course is aimed to be delivered through the NAFEMS Learning Hub, consisting of text, formulas, figures, videos, and downloadable files. Further specification and support will both be provided by the NAFEMS technical and marketing teams.

Cost

The total cost is not expected to exceed £6000 (GBP), and it is expected that the document 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. 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.
