Toughness index formula
WebWater content of the soil in natural condition. I l = W − W p I p × 100. When soil is at plastic limit, the liquidity index is 0. It is also called as water plasticity ratio. 3. Consistency Index:- ( I c, C I) Soil indicates nearness of water content of soil to its plastic limit. I c is zero at liquid limit. I c is 100% → When soil is ... WebToughness Index = plasticity index/flow index. Shrinkage Index = Liquid limit-shrinkage Limit. Except (C),(D) all are correct. Shariful (AMIEB) said: 3 years ago. The ratio of the plasticity index to the flow index (not flow limit), is known as the toughness index of the soil. Kamran Iqbal said ...

WebToughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of toughness (for high-strain rate, fracture toughness) is that it is a property that is indicative of a material’s resistance to fracture when a crack (or other stress-concentrating defect) is present.Toughness is typically measured by the Charpy test or … WebThe result of the INDEX function is a reference and is interpreted as such by other formulas. Depending on the formula, the return value of INDEX may be used as a reference or as a value. For example, the formula CELL("width",INDEX(A1:B2,1,2)) is equivalent to CELL("width",B1). The CELL function uses the return value of INDEX as a cell reference.
