Asymptotic method was adopted to obtain a receptivity model for a pipe Poiseuille flow under periodical pressure, the wall of the pipe with a bump. Bi-orthogona
The classical linear instability theory was applied to the planar stratified two-layers flow with high speed compressible gas layer impacting on incompressible
The three-dimensional frame is simplified into flat plate by the method of quasi-plate. The nonlinear relationships between the surface strain and the midst pla
The nonlinear constitutive equations and field equations of unsaturated soils were constructed on the basis of mixture theory.The soils were treated as the mixt
