Abstract

In the paper, optimization solution algorithm is developed, for the lam- inated cylindrical shell from composite materials. The free variables are prestressing forces in reinforcing wires (fibers) and the angle of their devia- tions from a canonical direction. The reason for the choice of such variables consists in increasing of the bearing capacity of the structure and in the fact that the local stress states in those structures are affected by processing and subsequent cooling to the room temperature. Consequently, serious troubles may arise, e.g. due to kinking of fibres when no prestressiug is applied. For the formulation and the solution of this relatively important problem, a new procedure is used, introduced in [1], which is called the transformation field analysis. 1 Introduction In the
