Crash Cad Calculate (CCC) is an unique software for design and optimization of thin walled beams cross sections in a user friendly 2D environment. In the CCC software the user can design and calculate cross sections, edit their material and compare results. CCC provides also the possibility to optimize the geometry of a cross section using the Cross Section Optimizer.
CCC is based on the macro element method worked out (among others) by T. Wierzbicki, W. Abramowicz and N. Jones in late eighties of the last century. The computerized version of the current macro element theory is based on the works of Wlodek Abramowicz.

Crash Cad Calculate features

Crash Cad Calculate provides a unique 2D environment for design and testing of Cross Sections of thin walled beams. Features and tools included in CCC enable the user to model and analyze the geometry of a cross section, define the used material, compare and report results of various designs. Moreover the user has the possibility to automatically optimize the geometry of a cross section.

Main features available in Crash Cad Calculate are:

  • Cross Section Editor – the Cross Section Editor is used to design, calculate and optimize Thin Walled Cross Sections for best crash performances. A number of edit tools are available which will enable the user to easily modify the geometry of a cross section.
  • Moreover the software provides Design Recommendations which help the user to achieve best crash performance of the designed cross section.
  • CCC Cross Section Editor provides also the possibility of Trigger design. Trigger is a local dent that initiates the desired progressive folding mode and reduces the peak load.


Results of calculations for a cross section are grouped in 6 categories:

  • Axial Response
  • Design Recommendations
  • Bending
  • Elastic Properties
  • Lateral Response
  • Denting
  • Torsion Response
