CADFEM ANSYS Extension for Fatigue Analysis according to FKM Guideline with material database

Strongly integrated into ANSYS

The FKM guideline was developed by the Advisory Board for Engineering and Research for various applications in mechanical engineering and other sectors. FKM inside ANSYS allows the local Fatigue Analysis to be supported by this widespread computational algorithm within ANSYS Workbench, including in the form of parameter studies during change of material or surface treatment. As a complement, FKM inside ANSYS contains the WIAM material database for quick generation of material cards inside ANSYS Workbench.

Convincing tools

  • WB/FKM – global, directive-compliant Fatigue Analysis of non-welded solid bodies according to FKM
  • WB/FKM-Weld – Fatigue Analysis of seam welds in shell structures according to FKM
  • WB/WIAM fatigue RIFEST – Fatigue Analysis at test points for welded and non-welded components according to FKM
  • WB/WIAM Engineering Data – material database for metallic materials

WB/FKM

Global, directive-compliant Fatigue Analysis, integrated into ANSYS Workbench, of non-welded solid bodies according to FKM

A frequent challenge in FEM is the evaluation of stress results, in particular with cyclic stresses. The FKM guideline “Analytical Fatigue Analysis for machinery components” describes a static Fatigue Analysis as well as a cyclic fatigue and/or fatigue limit test. WB/FKM facilitates the evaluation of an FEM analysis by carrying out a global Fatigue Analysis according to the FKM guideline for the analytical models.

This has the following advantages over a physical test, for example:

  • The complete integration in ANSYS Workbench enables fast and simple definition of the test parameters.
  • The global test permits a fast and safe location of critically stressed points.
  • The visualization of the load factor facilitates advanced interpretation of the results.

 

WB/FKM-Weld

Directive-compliant Fatigue Analysis , integrated into ANSYS Workbench, of weld seams on shell structures according to FKM

Analogous to the WB/FKM module, WB/FKM-Weld also facilitates the evaluation of stress results for cyclic stresses based on the FKM guideline “Analytical Fatigue Analysis for machinery components” through a static test and a cyclic fatigue and/or fatigue limit test.

WB/FKM-Weld covers the strength analysis of welded shell structures and also offers the following advantages:

  • The complete integration in ANSYS Workbench enables fast and simple definition of the test parameters.
  • User support during a search for and definition of weld seams.
  • Presentation of results facilitated with visualization of the degree of utilization.

 

WB/WIAM fatigue RIFEST

Fatigue Analysis integrated into ANSYS Workbench at test points for welded and non-welded components according to FKM

Integrated into ANSYS Workbench, the WB/WIAM fatigue RIFEST module supports the use of various Fatigue Assessments during component stress analyses. Among them are strength and fatigue limit tests according to the FKM guideline and the simulation of test points for welded and non-welded components. The module offers the capability of conducting quick, uncomplicated, parameter studies – such as variation of material selection, seam welding notch selection, or surface treatment – accelerating the verification process.

The most important functions of the module are:

  • Fatigue Assessment as a strength or a fatigue limit test, including the required static Fatigue Analysis
  • Fatigue Analysis for individual test points on the basis of existing local elastic stresses (such as those available from FEM simulations or strain gauge measurements)
  • extensive database of welded and non-welded machinery components: Rolled steel, iron casting material, aluminum material (including material properties)
  • normal and high temperatures

 

WB/WIAM Engineering Data

WIAM metallic material database integrated into ANSYS Workbench

The convenient WB/WIAM Engineering Data material database is based on the WIAM METALLINFO data pool and thus contains an extensive, up-to-date range of materials in one location. The material data includes norm history and international recoding.

The database is notable for the following:

  • direct data import into ANSYS Workbench
  • German and European standardization
  • TÜV material performance sheets
  • Steel and iron list and material data sheets, including those from manufacturers
  • FKM guideline
  • Ring trials and trial series at recognized universities
  • Technical literature
  • with sources comprehensively and precisely cited
