Hi ! I am a French PhD student on the optimization of mechanical structures. My objective is to derive a method for the pre-sizing of stiffened fiber composite space launcher structures. The aim of the thesis is to simultaneously optimize the stiffening paths and the composite stacking sequence of a launcher primary structure. I would be glad to exchange with you on various subjects (e.g. CAD, optimization, composite design, aeronautics, space launcher, ....) so do not hesitate to ping me ! Have a great congress !
