buckling instability

基本解釋

For pined_pined, loosed midpoint support plate, it is found that the plate's buckling instability will happen first while the flutter instability will disappear.
發(fā)現(xiàn)板在兩端簡(jiǎn)支、中點(diǎn)聯(lián)結(jié)松動(dòng)時(shí)，結(jié)構(gòu)首先出現(xiàn)屈曲失穩(wěn)，而不會(huì)發(fā)生顫振失穩(wěn)。
Compared with 535 ℃ solid-liquid phases and invariable pressure diffusion bonding, the new method can avoid hot crack and plastic buckling instability effectively.
與535℃固-液相恒壓擴(kuò)散焊相比，可有效地避免失穩(wěn)變形與熱裂紋。
Simulation results show that the abrupt buckling modes originate from the sudden release of strain energy due to the instability of SWCNTs at the critical buckling curvature.
我們的模擬結(jié)果表明，突變主要對(duì)應(yīng)于單壁碳納米管在彎曲載荷下的突然失穩(wěn)和應(yīng)變能釋放；
