RHEO-STAUB User Manual

Abstract:

RHEO-STAUB is a 2-D Finite Element Program which runs under Windows-95. It is tailored to solve problems in Geomechanics. Ist power is based on a nearly arbitrary material model which may be defined by the user at input time. Thereby, it is possible to take into account anisotropy, visco-plasticity, kinematic hardening and softening etc.

material model

RHEO-STAUB is suitable for the computation of plate structures under plane stress or plane strain conditions of arbitrary geometry and loading conditions according to the Finite Element method. A special feature of the program is based on the possibility to account for a variety of material models according to the users requirements. Flexibility of modeling is achieved by use of mechanical models, defined by a suitable combination of a few basic elements which idealize elastic, plastic, viscous and swelling behavior. Due to a special, civil engineering-oriented input language, the data input is easy to manage and extremely lucid. It is carried out with any text editor, thereby facilitating parameter analyses with a minimal expenditure. Great importance has been attached to a comprehensive graphical representation of the results. This is handled automatically by the program, thus enabling an easy interpretation of the resulting, sometimes rather voluminous amount of data.

Remarks:

A self extractable and installable version of RHEO-STAUB may be downloaded from our FTP server (2.4 MB). This version serves for both as an update for registred users with a dongle, and as a fully functional version (but with limited allowed problem size) for unregistred users.
Further information is available from a leaflet (either in form of a nice version based on a Java applet, or a simple version based on pure HTML).
NB: the 1st edition of RHEO-STAUB for DOS appeared1982/1983, c.f. IGT-no. 82-8, 83-1
