Optimal thickness of a cylindrical shell under dynamical loading
نویسنده
چکیده
In this paper an optimization problem for a cylindrical shell under an applied dynamical loading is discussed. The aim is to look for an optimal thickness of a shell to minimize the deformation when the shell is subject to an external timedependent force together with an initial impact. The volume of the shell has to stay constant during optimization. A model for the deflection is derived and analyzed and a corresponding optimal control problem is formulated. Numerical solutions are presented for a cylindrical panel with a body falling down onto the opposite side of the shell’s only clamped edge and then staying there.
