Mechanics of chain-link wire nets with loose connections

摘要: Abstract Chain-link wire nets are used for slope stabilization, natural hazard protection systems, mine and tunnel safety many other important applications. In rockfall barriers the designed to withstand dynamic, impulsive loadings. As they composed of ultra-high strength steel wires with loose three-dimensional connections, high resistance very flexible serve efficiently distribute loads throughout structure. Rockfall barrier design requires accurate numerical simulations. this work, a Finite Element model chain-link is developed. To treat complex contact interactions among elements components we develop computational scheme relying on general algorithm. The non-linear force displacement response net obtained in tensile quasi-static laboratory tests successfully reproduced by model. parameters optimization techniques. calibrated shown simulate full-scale test barrier. schemes allow us accurately mechanical behaviour connections.
