Abstract
The research results of the resistance to the deformation and destruction of fiber glass-plastic tubular elements with the reinforcement angle φ=0 0 (the direction of glass-fiber warp and the tube axis are coincided) subjected to the complex loading of twisting moment and inner hydrostatic pressure are brought and discussed. The following is determined that the increase of the twisting moment rate acting during the testing constantly is led to the decrease of resistance to destruction with valuable damping speed for glass-plastic tubes subjected to inner hydrostatic pressure. It is detected that during the loading by inner hydrostatic pressure for tubes subjected to constant twisting moment, shear and longitudinal strains along with the basic radial strain are appearing and developing. The characteristic properties of the resistance to the deformation and destruction of fiber glass-plastic tubes subjected to the consequent loading by twisting moment and inner hydrostatic pressure for the case of twisting moment applied primarily are discussed.
