The boundary element method was improved for the 2D elastic composites with randomly distributed inclusions. This problem can be reduced to a boundary integral
Using hybrid perturbatin-Galerkin technique, a circular cross-section tube model with sinusoidal wall is studied. This technique can remove the limitation of sm
Three kinds of forebody model of hypersonic vehicles were studied with numerical simulation method. It shows that the two-order compressive ramp model is the be
For a class of nonlinear filtration equation with nonlinear second-third boundary value condition, it is shown that a priori boundary of the solution can be est
A systematic study was made on the topological nature of the system of non-static rotating fluid. Several initial (boundary) value problems and their well-posed
Both the primary resonant solutions and their bifurcations due to time delayed velocity feedbacks used in a self-sustained oscillator with excitation were furth
From the molecular current viewpoint,an analytic expression exactly describing magnetic field distribution of rectangular permanent magnets magnetized sufficien
