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
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 .
Plane Strain versus Plane Stress
in the Mechanical Bidomain Model.
where [bar.[theta]] is the normalized Lode angle parameter It is expressed, under plane stress
condition, as follows,
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:
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.
Li reported that the fracture criterion for shell elements, assuming plane stress
, had two peaks for equivalent fracture strain at 1/3 and 2/3 of stress triaxiality.
