Tonus enables you to create sections and calculate their geometric properties on the basis of the thin-walled rods theory.
The graphical interactive tools enable to create arbitrary thin-walled sections (including mixed open-closed ones). The application enables to import the sections from the DWG or DXF file formats, and to work with the parametric sections specified by the user.
The following main characteristics can be obtained in the result of the calculation — cross-sectional area, values of the moments of inertia, radii of gyration, section moduli, torsional and sectorial properties, coordinates of the shear center.
Tonus enables to obtain the fields of normal stresses if the internal forces in the section have been specified.
The calculated geometric properties can be used in SCAD when specifying the stiffness properties of the elements.
Interface
Tonus functions under Windows operating environment. All the windows, dialog boxes and controls are fully consistent with this environment.
