RF-LAMINATE 4.xx

Design of Laminate Surfaces 
The add-on module RF-LAMINATE is used to perform deflection analyses and stress designs for laminate surfaces. The calculation taking into account shear coupling follows the sandwich (laminate) theory. Based on a user-defined layer structure, the program creates a local overall stiffness matrix for the respective surface.

Take advantage of RF-LAMINATE to design for example cross laminated timber elements, or to calculate layer elements used in concrete constructions or structures consisting of different elements.
Features

  • General stress designs
  • Graphical and numerical output of stresses and stress ratios completely integrated in RFEM
  • Flexible design in different design cases
  • High efficiency due to few data required for input
  • Flexibility due to detailed setting options for basis and extent of calculations
  • On the basis of the selected material model and the layers contained within, RF-LAMINATE generates a local overall stiffness matrix of the surface in RFEM. The following material models are available:
    • Orthotropic
    • Orthotropic user-defined
    • Isotropic
    • Isotropic user-defined
    • Hybrid (for combinations of material models)
  • Option to save frequently used layer structures in a database
  • Determination of basic, shear and equivalent stresses
  • In addition to the basic stresses, RF-LAMINATE shows the stresses according to DIN 1052 as well as the interaction of those stresses in the results tables.
  • Stress design for structural parts of almost any shape
  • Equivalent stresses calculated according to different approaches:
    • Shape modification hypothesis (von Mises)
    • Maximum shear stress theory (Tresca)
    • Maximum principal stress criterion (Rankine)
    • Principal strain criterion (Bach)
  • Calculation of transversal shear stresses according to Mindlin, Kirchhoff, or user-defined specifications
  • Serviceability limit state design by checking surface displacements
  • User-defined specifications for limit deflections
  • Detailed output showing the various stress components and ratios in tables and graphic
  • Output of stresses for each layer in the model
  • Parts list of designed surfaces

Input

Load cases, groups and combinations can be combined in various design cases for the design of the ultimate and the serviceability limit state.

First, select the surfaces relevant for the design by using the pick function before you define the appropriate material model. The structure of layers forming the basis for the stiffness calculation, can vary. The parameters defined by the selected material model can be adjusted. The 3*3 matrix of the layers can be modified as well. In this way, RF-LAMINATE ensures a completely free selection when generating the stiffnesses.

The limit stresses of each layer is defined by the selected material. It is possible to adjust the values by user-defined specifications.

Results 

Subsequent to the design, RF-LAMINATE displays the maximum stresses, stress ratios and displacements, sorted according to load cases, surfaces or grid points. The stress ratio can be displayed for any kind of stress type. The location currently active is highlighted in the RFEM analysis model.

In addition to the results evaluation in tables, it is possible to represent the stresses and stress ratios graphically in the RFEM work window. The colors and values assigned in the panel can be adjusted appropriately.
