Trajectory planning for a quadrotor helicopter
Yasser Bouktir,M. Haddad,Taha Chettibi +2 more
- 25 Jun 2008
TL;DR: In this article, a simple direct method able to generate time-optimal trajectories for a micro quadrotor helicopter is presented, which is based on modeling the quad-rotor trajectory as a composition of a parametric function P(λ) defining the path, and a monotonically increasing function lambda(t), specifying the motion on this path.
Prediction of necking in thin sheet metals using an elastic–plastic model coupled with ductile damage and bifurcation criteria:

TL;DR: In this paper, the conditions for the occurrence of diffuse and localized necking in thin sheet metals are investigated and the prediction of these necking phenomena is undertaken using an elastic-pla...
Investigation of ductility limits based on bifurcation theory coupled with continuum damage mechanics
Yasser Bouktir,Yasser Bouktir,Hocine Chalal,Hocine Chalal,M. Haddad,Farid Abed-Meraim,Farid Abed-Meraim +6 more
TL;DR: In this paper, the ductility limits of an St14 steel are investigated using an elastic-plastic-damage model and bifurcation theory, where an associative J2-flow theory of plasticity is coupled with damage within the framework of continuum damage mechanics.

Minimum time trajectory planning for a micro quadrotor aerial robot
Yasser Bouktir,Taha Chettibi +1 more
- 12 Jun 2008
TL;DR: In this article, a simple direct method able to generate minimum time trajectories for micro quadrotor aerial robots is presented, based on modeling the quadrobot trajectory as a composition of a parametric form P(λ) and a monotonically increasing function λ(t), specifying the motion on this path.
