The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- How can I deduce the axial stress and hoop stress of a circular container?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears sayng that the value is out of the valid range (existing value: 160, minimum value 200). What does this message mean?
- I have calculated a box beam. Which surface results or surface stresses can I use to evaluate the buckling behavior of the web plates?
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- For the settlement calculation in the RF‑SOILIN add-on module, the specific weight gamma and gamma,sat are required for the soil. What do I need the value gamma,sat for, and how is it assumed in the calculation?
- How can I display membrane stresses in the results of RF‑STEEL Surfaces?
- How does the "Orthotropic Plastic" material model work in RFEM?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
