WebThis paper is concerned with the elasto-viscoplastic constitutive equation of normally consolidated clay. A three dimensional constitutive equation is derived based on the Perzyna's elasto-viscoplastic theory and Cambridge theory. Comparing the theoretical results with the experimental results by triaxial compression test, it becomes evident that … http://ethesis.nitrkl.ac.in/7578/
WebThe experimental work was carried out to select the optimum percentage of each type of the used nanomaterials, and fibers to achieve the highest compressive strength and low cost. In this work, nineteen concrete mixes were prepared. Nano silica (NS) and nano clay (NC) were used at 0, 1, 2, and 3 % by weight of cement.
