Fascinating customer projects designed with the Dlubal structural analysis software.

The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses.

During the stress analysis, the add-on determines the maximum stresses of solids, surfaces and surface sets (RFEM only), as well as members and member sets. The governing internal forces are also documented for each member. In addition, there is the option of an automatic section or thickness optimization including the export of the modified sections or surface thicknesses to RFEM/RSTAB.

Features for Surface and Solid Design

  • Determination of principal and basic stresses, membrane and shear stresses, as well as equivalent stresses and equivalent membrane stresses
  • Stress analysis for structural surfaces including simple or complex shapes
  • Equivalent stresses calculated according to different approaches:
    • Distortion strain energy hypothesis (von Mises)
    • Shear stress hypothesis (Tresca)
    • Normal stress hypothesis (Rankine)
    • Principal strain hypothesis (Bach)
  • Optional optimization of surface thicknesses and data transfer to RFEM
  • Output of strains
  • Detailed results of individual stress components and ratios in tables and graphics
  • Filter function for solids, surfaces, lines, and nodes in tables
  • Transverse shear stresses according to Mindlin, Kirchhoff, or user-defined specifications
  • Stress evaluation for welds at connection lines between surfaces (see the Product Feature)

Results

After the calculation, the resulting maximum stresses and stress ratios are displayed sorted by section, member/surface, solid, member set, x-location, and so on. In addition to the tabular result values, the corresponding cross-section graphic with stress points, stress diagram, and values is displayed as well. The design ratio can be related to any kind of stress type. The current location is highlighted in the RFEM/RSTAB model.

In addition to the tabular evaluation, it is possible to graphically check the stresses and design ratios on the RFEM/RSTAB model. It is possible to individually adjust the colors and values.

Result diagrams of a member or set of members facilitate targeted evaluation. Furthermore, you can open the respective dialog box of each design location to check the design-relevant section properties and stress components of any stress point. You can print the corresponding graphic, including all design details.

Special Solutions

First, the two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Second, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
