Trainings and Seminars to improve your strength and test performance

Straddling the fields of industry and research, our engineers build on knowledge that has grown through decades of extensive interdisciplinary practice and development. Theoretical or experimental proofs of strength are one of our core concerns. Demonstrating the reliability and safety of the material for the whole life of the component is a challenging task for computation engineers, designers and testers.

Benefit from our cross-industry expertise: in training sessions and seminars at your premises or at our offices, you will receive comprehensive specialist knowledge and concrete application recommendations

On this page you will find information about the following IMA training sessions:

Background and Application of FKM Guideline

It is published by Forschungskuratorium Maschinenbau e.V. (FKM). As the guideline was issued under the leadership of IMA Materialforschung und Anwendungstechnik GmbH, you can get first-hand information at our seminar.

The aim of the seminar is to impart the methodology and the background of the analytical strength assessment according to FKM guideline. Find out more about:

the uniformly structured, analytical algorithm consisting of instructions, formulae, tables and diagrams
the static strength assessment and fatigue strength assessment, the latter depending on stress-time characteristics with constant or variable amplitudes
the scope of application for special alloys of the material groups steel, cast iron and aluminium alloys
the application for welded and non-welded components
the evaluation of nominal stresses and local, linear-elastically determined stresses from analytical calculations, finite element analysis or measurement

FKM guideline in practice

The FKM guideline “Analytical strength assessment of machine components” applies to mechanical engineering and related fields of industry and allows analytical strength assessement based on nominal stresses and local elastic stresses, taking all of the relevant influences into account. It is published by Forschungskuratorium Maschinenbau e.V. (FKM). As the guideline was issued under the leadership of IMA Materialforschung und Anwendungstechnik GmbH, you can get first-hand information on the methodology and the background of the analytical strength assessments as well as on the application and determination of input values in practice at our seminar.

In addition to the topics, which are also covered in our seminar “Background and Application of FKM Guideline”:

the uniformly structured, analytical algorithm consisting of instructions, formulae, tables and diagrams
the static strength assessment and fatigue strength assessment, the latter depending on stress-time characteristics with constant or variable amplitudes
the scope of application for special alloys of the material groups steel, cast iron and aluminium alloys
the application for welded and non-welded components
the evaluation of nominal stresses and local, linear-elastically determined stresses from analytical calculations, finite element analysis or measurement

this seminar also covers the challenges:

of modelling for the FE analysis,
of determining input values for the assessments, and
of interpretation of the assessment results.

Ansys Workbench is exemplarily used as finite element analysis software (no software training). The strength assessments are performed with the software WIAM®fatigue Rifest, which allows method assured strength assessments according to FKM guideline.
