1993
Etienne Balmes’s PhD defense
Etienne’s PhD thesis “Experimental/analytical predictive models of damped structural dynamics” contains the identifications algorithms (later called IDRC and IDRM) that were the first blocks of what was about to become the SDT.
1995
Structural Dynamics Toolbox
The Structural Dynamics Toolbox (SDT) is sold by Scientific Software Group (now The MathWorks, France)
2001
SDTools company
Creation of the SDTools company to transform the original SDT academic toolbox into a professional product and start consulting activities.
2001-2008
Hosting at Ecole Centrale Paris
SDTools has collaborated with the MSSMat Laboratory (now LMPS) of Ecole Centrale Paris, where Etienne Balmes headed the Vibration research group
2002
OpenFEM library
SDTools partnered with INRIA to combine efforts in the development of a general-purpose multi-physics finite element library OpenFEM. This joint effort greatly augments the number of people involved in developing FEM capabilities distributed with SDTools products.
