    Case Studies Demonstrating Industrial Usage of Engineering Analysis & Simulation  


    Introduction

    The NAFEMS Education and Training Working Group (ETWG) wishes to commission a new document with the suggested title of “Case Studies Demonstrating the Industrial Usage of Engineering Analysis & Simulation”. 

    This volume of case studies is intended to be used by academic course directors. The publication is expected to provide a set of case studies that demonstrate how engineering analysis and simulation is being used in industry and the benefit that can be obtained. The case studies should demonstrate the role and importance of verification and validation in the analysis process and demonstrate possible pitfalls that an inexperienced user can encounter. Suggested pitfalls that could be explored are:

    • Inappropriate mesh refinement
    • Element selection
    • Mesh distortion
    • Lack of sensitivity studies on key parameters i.e. penalty stiffness in a contact algorithm 
    • An incorrect assumption e.g. the assumption that dynamic effects were not significant


    Content

    This book should be aimed at a graduate-level industrial user who is familiar with basic linear FE analysis but is inexperienced in advanced FE simulations. The book should assume little or no knowledge of the equilibrium finite element (EFE) formulation. The following topics are expected to be included:

    • Introduction. This should lead the reader into the virtue of the EFE formulation by presenting the idea that the conforming finite element (CFE) formulation only satisfies equilibrium in a weak sense and the implications of this to engineers; a strongly equilibrated solution is essential for most structural design work.

    • A brief history of the EFE formulation.

    • Theoretical foundation of the EFE formulation. This should be presented in an approachable manner, starting with the potential problem, e.g., for heat conduction or torsion, and leading into linear elasticity for planar problems.

    • Use of EFE for lower-bound limit analysis.

    • Use of EFE for error estimation in CFE models.

    • Extension to non-linear problems.

    • Some examples of EFE analysis. 


    Format

    The publication is not intended to provide a set of tutorials but proposals that include material that would help the course director develop their own tutorial based on the case study will be viewed favourably. Input data that could be difficult for the course director to generate (such as geometry files) would be a useful output to accompany this publication.  


    Cost

    The total cost is not expected to exceed £6K (GBP), and it is expected that the document will be completed within 12 months from NAFEMS approval.


    Proposals

    Each proposal should consist of:

    • A description of each of the case studies that will be included in the publication
    • The proposed structure that would be used to describe a typical case study
    • Work plan including milestones and interim deliveries for early review
    • Cost
    • The authors' credentials, curriculum vitae, etc. 
    • A list of the NAFEMS PSE competency that the publication will address

    Proposals from single authors and consortia will be considered.


    Submission 

    All proposals should be sent to NAFEMS at etwg@nafems.org to arrive no later than 1st January 2018. Further details are available from the NAFEMS Technical Officer and the ETWG chairman who are contactable through the etwg@nafems.org email address.
