Sentence examples for the dilation angle from inspiring English sources

The plastic flow rule is controlled by the plastic potential and expressed by Q = p^{prime}sin psi_{{_{p} }}^{omega } + Jleft( {cos theta - frac{{sin theta sin psi_{{_{p} }}^{omega } }}{sqrt 3 }} right) - C_{text{p}}^{omega } cos psi_{text{p}}^{omega } = 0 (17)(psi_{text{p}}^{omega }) is the dilation angle which describes the transition between plastic compressibility and the plastic dilatancy.

The factor of safety of a slope is influenced by the dilation angle.

Their post-yield behavior follows the non-associated flow rule defined by the dilation angle.

(1) The dilation angle ψ is a ratio of vertical shear strain increment and strain increment, which is taken as 38 degrees.

In the FE model it is also necessary to define the dilation angle, but as associated flow was assumed it follows that φ = β.

It is illustrated from a few examples that displacement distributions obtained from the dilation angle model are more reasonable when compared with the general trend measured underground.

The dilation angles predicted from best-fit dilatancy curves are sensitive to the base distance or shear displacement.

They also indicate that the soil dilation angle influences the value of N′γ when the soil displays high nonassociativity for large internal friction angle values.

If the same dilation angle is considered, comparisons of the plastic potential surfaces determined by Eq. (9) in this paper and the potential surface proposed by Menétrey William [16] and employed in the embedded M C model in ABAQUS are shown in Fig. 6.

For the case history, a 2D finite element analysis was performed to back-calculate the effective dilation angle assuming no cohesion was present and the basic friction angle was 25°.

The calibrated dilation angle and concrete damage factor were validated by experimental investigations of the specimens subjected to cyclic loadings; the required stiffness of the column metal plates for rigid joints was identified.
