| Summary |
The mechanical properties for collapsing process of inflatable tube subject to bending load are investigated by FEM analyses. The periodic wrinkles emerges at first on the compressive side of the inflatable tube as the bending lad increased, when the axial stress reaches the buckling stress of cylindrical shell structures. As bending load increases further, some isolated wrinkles occur and the periodic wrinkles disappear. The stress fields and geometrical properties of the wrinkling and collapsing inflatable tube is also discussed in detail.
