It points out that the key to the technical process of the product manufacturing lies in meeting the requirements of separating strength and the easily torn ability.

The vague neural network applied in analyzing tearing property of fabric is discussed in this paper.

A quasi static approach is presented for ductile tearing test of double cantilever beam specimen by using the model of elastic beam on elaso plastic foundation.

The specific fracture energy for ductile tearing crack propagation in three kinds of pipeline steel was experimentally determined at room temperature under quasi-static and dynamic loading conditions using pin-loaded side-grooved double cantilever beam (DCB) specimens.

The tearing behavior of ballonet material and the ability of reinforced tendon for preventing tear from propagating were experimentally studied,and the unsteady flow field around an after-burst airship was also numerically simulated.
