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.
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.
Gao, "A mathematical analysis of the elasto-plastic
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.
