But the stress - strain relationship is in complex stress condition after the necking starts 但是,從頸縮開始,其應(yīng)力應(yīng)變關(guān)系處于復(fù)雜應(yīng)力狀態(tài)。
The complex stress calculation formula , after starting of necking in simple tension experiment , is deduced in the paper 導(dǎo)出了單向拉伸試驗(yàn)頸縮開始后復(fù)雜應(yīng)力的計算公式。
Moreover , there is not the value of ihe influence of loading rates on the behavior of concrete in the states of complex stresses 另外,規(guī)范中也沒有復(fù)雜應(yīng)力狀態(tài)下加載速率對混凝土性能影響的指標(biāo)。
The problem of ductile fracture of metals under complex stress has been investigated extensively , but has not been resolved as yet 金屬材料在復(fù)雜應(yīng)力狀態(tài)下的韌性斷裂是斷裂力學(xué)研究的重要問題之一。
By pot growing method , effects of different salinity - alkalinity complex stress on tiller number and thy matter accumulation of rice were studied 摘要采用盆栽法研究了不同鹽堿度對水稻分蘗數(shù)、分蘗前期和分蘗末期干物質(zhì)積累狀況及產(chǎn)量的影響。
