Аннотация:A pipe made of composite material is considered. Two approaches are proposed.The first is based on the averaging method. In this case, an effective model is a model of ahollow circular cylinder. In the second approach, a one-dimensional beam is an effectivemodel. We also represent the problem of minimizing the weight of the pipe at fixed stiffness ofthe layers. The paper shows that this problem is equivalent to a well-studied nonlinearprogramming problem.
