Polymer Mechanics Aims and scope

Conclusions

1. The authors have developed a method of mechanically testing medium-sized vessels that takes into account their structural characteristics and the properties of the walls. The method is based on obtaining the mechanical characteristics by extending annular and cylindrical specimens and comparing the radial displacements calculated from the mechanical characteristics obtained with the radial displacements obtained by subjecting the vessels to internal pressure and axial tension. A comparison of the experimental and calculated data indicates good agreement.

2. As a result of the experiments and calculations, relations are obtained for the moduli of elasticity and Poisson's ratios as functions of the stress level.

3. The experimental procedure developed makes it possible not only to take into account the structure of the vessel but also to obtain the stress levels in the vessel walls, using the equilibrium equation.
