Large Viscoplastic Deformation of a Semicircular Arch under Impact
刚粘塑性半圆拱在落锤冲击下的大变形响应
Taking the tunnel as wave-guide, the finite element method was used to analyze a rectangular tunnel, semicircular arch tunnel and the effect of height of the electric locomotive on the cut-off frequencies of electromagnetic wave in the circular tunnel.
将巷道看作波导,利用有限元法,分析了矩形巷道,半圆拱形巷道以及圆形巷道中机车高度对电磁波截止频率的影响。
