The model calculation adopts the

plane stress model and uniaxial compression axial displacement loading.

The stiffness equation is obtained by superposing the equations of the DKMQ element and standard Q4

plane stress element.

Adopting the

plane stress assumption and the micromechanics model, the analytic model of residual stresses for hoop wound cylinder with an inner liner is established by considering the shrinkage stress and thermal stress.

The results of mining ground pressure in the physical model of

plane stress can clearly illustrate the mechanical behavior of the rock around the retained entry with stiff coal pillar under the hard roof [40].

Plane Strain versus

Plane Stress in the Mechanical Bidomain Model.

The extending direction of the soil slope is taken as the

plane stress state, and elastic half-space

plane stress analysis is performed for soil in a steady state under gravity stress; the main stress expression of any point is as follows:

plane stress problem of a power-law material," IMA Journal of Applied Mathematics, vol.

In this paper, free vibration characteristics of FGM ring under either the

plane stress or plane strain states were investigated by using the first-order shear deformation theory.
