This paper presents observed failure modes for a geobag structure from a series of physical modeltests. Six hundred bags were employed to observe the failure in terms of friction force, water depth, flow rateand bag aging. Three different failures are reported. An analysis of the effect of bag aging shows that 52% ofsaturated bags gain weight in the range 0 to 5% and about 70% of in...
Kevlar is a type of aramid fibers which is characterized by high strength to low weight ratio. This material is widely used in bulletproof vests and helmets, in which it creates a barrier to projectiles to protect specific objectives, laminated tubes and pressure vessels, etc. In this study the ballistic behavior of Kevlar /epoxy composite and Kevlar fabric is investigated. The results showed t...
In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...
