常見例句The characterless zone on the fracture is the shear band instead of fracture surface of shear crack. 斷口上的無特征區(qū)是剪切帶,而不是剪切裂紋斷口;TEM observation showed that the center of the adiabatic shear band (ASB) was composed of recrystallized nano-grains (about 30-70 nm in diameter). TEM觀察表明絕熱剪切帶(ASB)中心區(qū)域由30-70納米的等軸晶組成。Peak strength, mechanical behavior, and pattern of shear band (SB) of anisotropic jointed rock specimen were modeled by FLAC. 摘要采用FLAC模擬了節(jié)理傾角對各向異性巖樣峰值強度、力學行為及剪切帶圖案的影響。The formation mechanism of adiabatic shear band(ASB) produced by high speed penetration in 30MnCrNiMoB low alloy steel was studied. 研究了30MnCrNiMoB低合金鋼在穿甲彈沖擊下絕熱剪切帶(ASB)的形成機制。In this paper,the TEM research results on the rnicrcotructure of adia- batic shear band(ASB)in various metallic material have been reviewed. 本文總結(jié)了金屬材料中絕熱剪切帶微觀結(jié)構(gòu)的透射電子顯微(TEM)研究成果,其主要內(nèi)容涉及以下幾個方面:絕熱剪切帶微觀組織特征;The development of shear band was researched by analyzing the confining pressure-time history, volumetric curve and displacement field of PFC model. 通過分析圍壓-時步曲線、體變曲線和不同階段的顆粒位移場的變化規(guī)律,研究了剪切帶的形成與發(fā)展規(guī)律。 返回 shear-band
