1. This procedure for the plane deformation of non-linear finite element program can be used to calculate the earth dam, foundation, retaining walls or underground structure, stress and deformation.
2. Soil non-linear stress- strain relationship with Duncan hyperbolic model
The other elastic constants have two options:
(a) tangent Poisson s ratio:
(b) tangent bulk modulus:
3. Problem-solving approach the midpoint of incremental method, taking into account each of the two-stage loading calculated elastic constants for some units may vary widely, but the actual may be in between, so take two a weighted average calculation of elastic constants, as amended, including the right to take the initial elastic constants of 1/4, the midpoint of the right of elastic constants obtained for the 3/4, to reflect the average of the results of close to the midpoint of elastic constants.
4. Quadrilateral grid parameters such as arbitrary units.
5. The program contains one-dimensional contact eleme
