Certain composite materials or high-polymers are known to behave differently in tension and compression. Little attention has been paid to these materials except for certain materials, such as concrete. Since composites or high-polymers serve as structural elements, problems of plates or shells of such materials have practical importance. This paper presents an example of an axisymmetric deformation analysis of a simple shell problem involving a bimodulus orthotropic circular cylindrical shell subjected to a uniform internal pressure. Numerical results obtained by a successive approximation method show that the state of stress in the cylinder is affected significantly by different moduli in tension and compression, especially by those in the circumferential direction.
