Predicting the lifespan of 3D printed metal parts

FATAM software is used to predict the service life of multiaxially stressed metal parts manufactured by 3D printing. FATAM SW allows both processing of data obtained from experimental tests and loading of data from computational SW. Currently, connectivity to the FEM simulation SW Siemens SIMCENTER is available.

A trial version of the program is available upon request by email info@techsim.cz with the company name and the applicant's first and last name.

The FATAM software was created within the project FW01010462 Computational and experimental support for 3D printing of metal components using DMLS technology and exposed to multiaxial fatigue loading in operation, in a joint effort of TechSim, RTI of the University of West Bohemia and STU in Bratislava.

The FATAM computational software is used to assess the fatigue strength and service life of multiaxially loaded machine parts based not only on the hypotheses of world-class authors, but also on our own developed models and experimental approaches in the field of material fatigue.

The FATAM program consists of 4 separate modules:

•  
• Module for processing and entering material parameters (direct entry of material parameters, processing measurements into the form of fatigue curves).
• Module for defining loads (defining the shape and type of load path, defining so-called calculation points).
• Module for defining the hypotheses and calculation procedures used for estimating fatigue life under multiaxial loading (multiaxial hypotheses, influence of the mean value, ...)
• Module for processing and exporting results.

 
SW FATAM offers several possible hypotheses and calculation procedures, proposed by various world authors as well as its own hypotheses. For criteria based on acting local stresses, these are, for example, the authors:

• Findley;
• McDiarmid;
• Matake;
• Carpintieri-Spagnoly;
• Margetin-Durka-Chmelko
• and others.

 
And for criteria based on acting local deformations, these are, for example, the authors:

• Fatemi-Socie;
• Brown-Miller;
• Smith-Watson-Topper;
• and others.

 
A detailed description of the program, including the SW architecture, a description of individual SW menus, and the procedures used for entering materials, loads, and calculation hypotheses, both foreign authors and our own multiaxial fatigue criteria, is provided in the FATAM SW User Manual, which is part of the installation files within the SW license.
