WebUnconsolidated – undrained tests were performed in the standard 38.1mm diameter triaxial cell, without the measurement of pore water pressure. Specimens of the undisturbed lateritic soil were first tested at 2%/min strain-rate. All tests on compacted specimens were carried out with controlled strain at the optimum moisture content. WebChange of size: bulk modulus; Change of shape: shear modulus; Uniaxial loading: Young's modulus and Poisson's ratio; Relationships between stiffness moduli. As stresses are increased or decreased a material body will tend to change size and shape as strains occur: stiffness is the relationship between changes of stress and changes of strain.
WebJun 1, 2024 · $\begingroup$ No, you can't assume that the bulk modulus just remains a constant for very high pressures, although the bulk modulus of water remains fairly constant for pressures as high as that at the deepest point in the ocean (about 1 kbar of pressure). For very high pressures of 10's or 100's of kbar or more, the bulk modulus cannot be … WebMay 22, 2013 · In the indicated Plaxis versions an issue exists with the calculation of the maximum value used for the bulk modulus of water when using non-metric units. This issue is only relevant for Undrained (A or B), Consolidation and/or Transient flow calculations and only when using stiffer (sand or rock like) materials. The effects will depend on the ...
