Hyperbolic parameters for compacted soils
WebHyperbolic formulation suggested by Duncan and Chang (1970) has been used extensively to describe the nonlinear stressŒstrain behavior of many soils prior to failure. Web1 apr. 2024 · The overall objective of this paper is to represent the nonlinear soil–pipe interaction using the hyperbolic parameters A and B as shown in Figure 1 b. As described by Wong and Duncan [ 23 ], the A and B parameters are related to the line of best fit when describing the hyperbolic curve.
