摘要

The experimental research on the static characteristics and fatigue characteristics of steel wire wound reinforced rubber flexible pipe under combined effect of internal pressure and transverse bending was carried our.The test results show that the axial tensile elastic modulus of flexible pipe is not equal to compressive elastic modulus.In the process of fatigue test,there is no downward trend in the axial elastic modulus of flexible pipe.In the light of various phenomena that happened in the fatigue test,the fatigue damage mechanism of flexible pipe was discussed.
