Kinematically Started Deformation (KSD) method for fast deformation computation of flexures

This video introduces the kinematically started deformation method, a method for the fast computation of statically deformed configurations of flexure mechanisms. Computing the deformation of a complex mechanism is up to 90 times faster than conventional methods.
