... of accidents and empirical formulas. The dynamic response process of large steel tanks impacted by fragments was simulated with ls - dyna . The typical impact process and results were analyzed in detail, and the damage laws of the tanks were discussed under various filling coefficients, volumes, fragment...

.... The experimental and numerical results show that water can effectively reduce the peak dynamic response of the steel plate and increase the vibration period of the steel plate. The center of the circular plate is the most dangerous position under confined blast loading, regardless of whether the plate is covered...

...Yuanqi Liu; Yang Du; Fan Zhou; Zhaoteng Zhang The deformation and dynamic response of a multilayer cylindrical shell composed of an inner shell and fourteen outer layers under external blast loads of different trinitro-toluene equivalency weights were studied. A numerical model using the thermo...

...Qi Sun; Qi Dong; Sha Yang The dynamic response of composite explosion containment vessels has been widely reported by experimental observations. In this study, we propose an analytical method to predict the dynamic response of open-ended cylindrical composite shells subjected to internal blast...

... 3 . The results obtained by experiments and present method are given in Table 4 . It is shown that analytical results and experimental data match with each other quite well. It is important for designers to know the thermo-elastic dynamic response of structures subjected to thermal stress...

... maximum bending stress for all of the loadings considered in analysis such as deadweight, constrained thermal expansion, dynamic response, etc. [ 8 ]. The coordinate systems shown in Fig. 5 represent the four locations where cracks were introduced. Note that these are on different legs so that they do...

...Atef Mohany; Victor P. Janzen; Paul Feenstra; Shari King This paper describes a test program that was developed to measure the dynamic response of a bundle of steam generator U-tubes with anti-vibration bar (AVB) supports, subjected to Freon two-phase cross-flow. The tube bundle geometry is similar...

... include remote impact analysis and parameter identification, pipe damage-induced by pressure elastic waves, the dynamic response and stability of long pipes, marine risers together with pipes aspirating fluid, and carbon nanotubes conveying fluid. In offshore industry, fluids are conveyed from...

...Q. Dong; Q. M. Li; J. Y. Zheng; B. Y. Hu Strain growth is a phenomenon observed in the elastic response of containment vessels subjected to internal blast loading. The local dynamic response of a containment vessel may become larger in a later stage than its response in the initial breathing mode...

... this model, dynamic response of the system under harmonic and that under random excitations are analyzed. Some numerical results are shown. Introducing a Fourier series expansion for the periodic function g ( θ ) as 6 g ( θ ) = ∑ n = 1 , 3 , … ∞ ( a n conn θ...

... a large-scale shake table which verified that the ties acted as energy-absorbing devices against severe earthquakes. Since recent boiler structures are designed based on dynamic response analysis considering the boiler-structure interaction and the effect of energy dissipation of the ties, it is necessary...
