MODELING OF ARCHING UNREINFORCED MASONRY WALLS SUBJECTED TO BLAST LOADINGS
… to limit the amount of wall damage is imposing arching mechanism on the wall. Since carrying out physical experiments to study the response of URM walls subjected to blast load is both dangerous and expensive, finite element modeling has become more attractive to researchers. In this research, …

Arching action and the ultimate capacity of reinforced concrete beams
… and analytical investigation into the effects of arching action on the ultimate capacity of reinforced concrete be is presented. In particular, the enhancement in the shear strength of which are longitudinally restrained is studied in detail.<br/><br/>Initially, a new rationally based design …

A new constitutive and numerical model for arching of cohesive powders in hoppers
… determination and numerical simulation. Cohesive arching at the outlet is a formation of an arch of cohesive powder (usually fine powder) at the smallest cross-section of a flow channel in a silo (usually the outlet). If it builds up the material inside of the silo, it can potentially cause the …

Development of new protocols to evaluate the transverse loading of mine ventilation stoppings
… of the sealant. A new protocol based on rigid arching is proposed to determine the true transverse load capacity of stoppings. Arching is achieved by the restraint of the stopping against the mine roof and floor, whereby compressive forces are developed within the wall. A laboratory procedure …

Experimental Investigation of Liquid and Particle -Laden Flows in Microtubes
… for 0.33 D < dp < 0.46D, a shear-induced arching mechanism has been observed, similar to the arching phenomenon common to granular flows. Orthokinetic flocculation occurs when shear-induced particle collisions result in particles attaching by surface forces to form large groups of …

Experimental Investigation of Micro-Channel Blockage Phenomena
… that blockage is triggered by a shear-induced arching formation, which does not require any flocculation prior to the arching formation. The experimentally determined non-dimensional scaling parameters from micro-glass capillary experiments suggest that the probability of blockage can be scaled …

Shamanic gender liminality with specific reference to the NatKadaw of Myanmar and the Bissu of Sulawesi.
… and so popular. Buddhism, however, is the over-arching factor. On Sulawesi, once again a combination of interviews and a study of the island’s history reveals the complexity behind the decline in numbers of the Bissu, the Bugis shamans. Again religion is the over-arching factor – in this case …

An EU-South African free trade agreement : how will South Africa benefit?
This paper will attempt to answer the over-arching question: Will South Africa benefit from a free trade agreement with the EU? It will not attempt thorough empirical analysis of this question. Instead, it will offer theoretical insight to certain of the policy questions raised about the proposed …

The effects of the pressure arch upon multiple seam mining

Centrifuge modelling of the behaviour of geosynthetic-reinforced soils above voids
… of the centrifuge test results showed that arching significantly reduces the stress at the base of the soil when a void forms; this mechanism is due to stress redistributions and not the formation of a physical arch. A new method to reliably predict this reduction was provided by calculating …
