Progressive damage analysis of single fastener joints in composite laminates considering the material nonlinearity 含材料非線性的復(fù)合材料單釘接頭累積損傷分析
To solve the nonlinear problem , such as material nonlinearity and geometrical nonlinearity , incremental method was used 為解決沖擊過(guò)程伴隨的材料和幾何非線性問(wèn)題,數(shù)值分析中采用增量法。
The result shows that the material nonlinearity affects the stability much more than the geometrical nonlinearity ' s does 結(jié)果表明:幾何非線性對(duì)該橋穩(wěn)定性影響較小,而材料非線性對(duì)穩(wěn)定性影響較大,這些結(jié)論對(duì)鋼管混凝土穩(wěn)定性分析具有指導(dǎo)意義。
The methods of geometrical nonlinearity and material nonlinearity analysis are discussed and common fem software is used to analyze the stability of certain railway bridge 摘要探討了鋼管混凝土拱橋幾何非線性和材料非線性穩(wěn)定性分析方法,并運(yùn)用通用有限元程序?qū)δ宠F路大橋進(jìn)行分析。
