This study investigates the effects of voids on the internally pressurized tangentially fiber reinforced tube with open and closed ends. As known, voids-induced errors in the fiber reinforced composites bring about degradation of the mechanical properties of the material. Due to the property degradations, the failure limits of the tube reduce. Herein, analytical approaches are performed to model elastic solutions and the material properties. Employing two different failure criteria, Tsai-Wu and Hoffman, the limit internal pressure values are found for the tube containing various void volume fractions. It has been observed that, as the void volume fraction in the composite rise, in other words, when void-induced defects increase in the tube, corresponding directional stresses and the limit pressure values of the tube decrease. Moreover, the location of the voids through the thickness of the tube may change the radial position of the failure. |
