...Zhangxian Yuan; George A. Kardomateas This paper presents an analysis for the dynamic stability of sandwich beams/wide plates subjected to axial impulsive loads. The formulation and solution of the problem is done by use of the extended high-order sandwich panel theory (EHSAPT). With the initial...

... engineering implications, parametric excitation of a structure with sequentially passing oscillators has not been well addressed. The dynamic stability in such a moving-oscillator problem, due to viscoelastic coupling between the supporting structure and moving oscillators, is different from that in a moving...

... of segment B are chosen as the reference parameters. In Fig. 9 , the circle (○), square (□) and triangle (△) curves are the dynamical stability curves of the material-periodic pipe, geometrically periodic pipe and the pipe with a combination of material and geometric periodicity, respectively...

...Tomasz Belica; Marek Malinowski; Krzysztof Magnucki This paper presents a nonlinear approach with regard to the dynamic stability of an isotropic metal foam circular cylindrical shell subjected to combined loads. The mechanical properties of metal foam vary in the thickness direction. Combinations...
