Analysis of Fuzzy Stress and Strength Reliability of Double-Layer Pressure Vessel

Abstract:

The deterministic analytic stress formula of double-Layer pressure vessels is derived. The optimum radius ratio between the inner and outer layers is obtained under uniform safety margins. Based on that, the method for evaluating the fuzzy stress and strength reliability is presented and an application example is given. The investigation provides a reference for further studies of uncertain mechanical problems of multi-layer pressure vessels
