ELASTIC MODULUS OF GEOGRID-REINFORCED SAND USING PLATE LOAD TESTS This paper describes an experimental study conducted to evaluate the elastic modulus of sand reinforced with polymeric geogrids. A total of 9 plate load tests were performed in the lab using a 1.52m by 1.52m by 1.37m test box, and a 0.3m square test plate.Get price

The results suggest that total and sand LWC shrank 20 and 5% more than the corresponding equal strength NWC, respectively. In spite of the differing values of shrinkage strains, compressive strength, modulus of rupture and modulus of elasticity of the concretes tested, the failure tensile strain capacity (extensibility) of all the concretes was somewhat similar.Get price

2004/1/9An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus.Get price

Young's modulus determines the mechanical loads required to elastically stretch a material and also the loads required to bend it, given that bending stretches one surface while compressing the opposite one. Flexoelectric materials have the additional property of becoming electrically polarized when bent. The associated energy cost can additionally contribute to elasticity via strain Get price
