Analysis & Design Software for Laminate and Sandwich Structures

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

Design of Laminate Surfaces

RF-LAMINATE performs stress and deflection analysis of laminate or sandwich surfaces under consideration of shear coupling (cross‑laminated timber elements, fiberglass, carbon, and so on).

  1. 1 - Cross-Laminated Timber Wall with Openings Subjected to Wall Stress

    Stability Analysis of Two-Dimensional Structural Components on Example of Cross-Laminated Timber Wall 1

    Basically, you can design structural components made of cross-laminated timber in the RF-LAMINATE add-on module. Since the design is a pure elastic stress analysis, it is necessary to additionally consider the stability issues (flexural buckling and lateral-torsional buckling).

  2. 1 - Structure of Layers with Stiffness and Strength Properties for Stora Enso CLT 100 C5s

    Stability Analysis of Two-Dimensional Structural Components on Example of Cross-Laminated Timber Wall 2

    The following article describes design using the equivalent member method according to [1] Section 6.3.2, performed on the example of cross-laminated timber wall susceptible to buckling described in Part 1 of this article series. The buckling analysis will be performed as a compressive stress analysis with reduced compressive strength. For this, the instability factor kc is determined, which depends primarily on the component slenderness and the support type.
