Numerical evaluation of buckling behavior in space structure considering geometrical parameters with joint rigiditySu-Deok Shon1, Kyung-Ju Hwang2, Seung-Jae Lee1(1. School of Architectural... behavior of single layer space structure is very sensitive. The joint rigidity, moreover, is one of the main factors of stability which may determine the entire failure behavior. Thus, the reasonable......

Effects of pitting corrosion on fatigue life of aluminum alloy Y12CZ based on initial discontinuity state YU Da-zhao(郁大照) 1, CHEN Yue-liang(陈跃良)2, HU Jia-lin(胡家林)1, YANG Mao-sheng(杨茂胜)1 1. Naval...: Based on initial discontinuity state (IDS) of material, a preliminary analytical model was presented to evaluate the effect of interaction of pitting corrosion and fatigue loading on the residual......
, the bistability of the structure disappears, and the second stable state changes into the local stable state, which means that in the whole traveling range, there is only one stable state at the original position... is the initial distance between the mass and the substrate. In Fig. 11, the time response of the bistable structure for the half-sine pulse force is obtained from the numerical simulation. The total response......
