Consideration of Plastic Deformations from Previous Load Situations

The RF‑LOAD‑HISTORY add‑on module for RFEM considers the permanent (plastic) deformation of previous load states. The calculation is performed for structural models consisting of surfaces or solids. Calculations in RF‑LOAD-HISTORY require the RF‑MAT NL add‑on module.

  1. Features

    • Simple definition of load steps
    • Simple assignment of load cases, load combinations, result combinations to load steps
    • Consideration of plastic deformations (isotropic hardening behavior) of previous load steps
    • Numerical and graphical display of results (deformations, support forces, internal forces, stresses, strains, etc.) for individual load steps
    • Detailed printout report including result documentation for all load steps
  2. Module window 1.1 General Data

    Input of Load Steps

    After defining the entire model and loading in RFEM, it is possible to enter load steps and descriptions in the 1.1 General Data window.

    In the 1.2 Loads window, you can assign load cases, load and result combinations to the different load steps. It is possible to multiply them by a load factor.

  3. Detailed settings for calculation


    The calculation is performed successively for each load step. Permanent (plastic) deformations of previous load steps are considered when calculating further load steps. In this way, it is also possible to perform a calculation with a structure relief.

    The loads of the individual steps are added up (depending on the signs) throughout the calculation process. You can freely select the method of analysis (linear static, second-order, large deformation, and postcritical analysis). Furthermore, the module manages the global calculation settings.

  4. Module window 2.21 Surfaces - Equivalent Stresses - von Mises

    Results and Export

    After the calculation, you can evaluate the results of the individual load steps directly in the module windows or graphically in a structural model.

    The results include for example deformations, stresses and internal forces of surfaces as well as deformations and stresses of solids. It is possible to export the result combinations for each load step to RFEM. You can use these enveloping combinations for further designs in the other RFEM add-on modules.

    All input data and results of the add-on module are part of the global RFEM printout report.
