A fluid with a constant density in a homogeneous gravity field exerts a hydrostatic pressure on its comprehensive container wall according to Pascal's law.
The deformations of the FE nodes are always the first result of an FE calculation. It is possible to calculate strains, internal forces, and stresses based on these deformations and the stiffness of the elements.
In RFEM 6 it is possible to save selected objects (as well as whole structures) as blocks and reuse them in other models. Three types of blocks can be distinguished: non-parameterized, parameterized, and dynamic blocks (via JavaScript). This article will focus on the first block type (non-parameterized).
Until now, if you wanted to determine the centroid of a rectangle, it was necessary to define a line from one corner point to the diagonally opposite point. You obtained the centroid by dividing this line. In RFEM 5 and RSTAB 8, you now have the possibility to create a node between two points. Thus, it is sufficient to select the corner points; then you can determine the distance in absolute or relative values.
In the Stress-Strain Analysis add-on, you can use the option to specify sign-dependent limit stresses by stress component.
Get a better understanding of the stress distribution within member cross-sections by using clipping planes.
The deformation process of the global deformation components can be represented as a movement sequence.
The results of solid stresses can be displayed as colored 3D points in the finite elements.
How can I additionally model welds for the connection of two surfaces with a contact solid?
In connection with a calculation according to the large deformation analysis, I get significantly smaller deformations than for a calculation according to the linear static or second-order analysis. How is this possible?
I have calculated a box girder. Which surface results or surface stresses can I use to evaluate the buckling behavior of the web plates?
How can I perform a stability/buckling analysis on a plate structure?
How can I connect surfaces to other surfaces or members in a hinged/semi-rigid way?
