The nonlinear calculation adopts the real mesh geometry of planar, buckled, simple curved, or double curved surface components from the selected cutting pattern and flattens this surface component in compliance with the minimization of distortion energy, assuming defined material behaviour.

Basically, this method attempts to compress the mesh geometry in a press assuming frictionless contact and to find such a state where the stresses due to flattening the component in the plane are in equilibrium. In this way, the minimum energy and the optimum accuracy of the cutting pattern are achieved. Compensation for warp and weft as well as compensation for boundary lines are considered. Then, the defined allowances on boundary lines are applied to the resulting planar surface geometry.

  • Minimization of distortion energy in the flattening process for very accurate cutting patterns
  • Application for almost all mesh arrangements
  • Recognition of adjacent cutting pattern definitions to keep the same length
  • Mesh application for main calculation
