Intralaminar Fracture Toughness Characterization of a Torn High Strength Cloth with Dyneema® Fibers

To investigate the damage tolerance of a flexible tsunami barrier, the intralaminar fracture toughness of a plain weave cloth, consisting of Dyneema© fibers and a plastomer resin, has been investigated.<br/>Fracture toughness tests have been performed on center cracked tensile specimens, with varying sizes and initial crack ratios, under quasi...

Design Study of a Flexible-Membrane Tsunami Barrier Concept

The inundation height of the Tohoku tsunami of 2011 exceeded the design levels of many coastal barriers and several structures collapsed. Hundreds of seawalls and breakers are (planned to be) (re)built in the Tohoku district. There is much debate about the conventional tsunami walls and it is therefore suggested to consider alternative tsunami...

Dynamic behaviour of a flexible membrane tsunami Barrier with Dyneema®

Proof-of-concept model tests on a novel self-deploying on-shore tsunami barrier were executed. The tsunami barrier consists of a membrane, floater and cables that are stored underground. Due to buoyancy the barrier self-deploys when struck by a tsunami. The membrane and cables consist of the strong, flexible and light-weight material Dyneema...
