Considering the Stiffness of Gas Solids in Nonlinear Time History Analysis

Technical Article on the Topic Structural Analysis Using Dlubal Software

  • Knowledge Base

Product Feature

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.
