Three types of adiabatic shearing bands, namely, the deformation band, the transformation bands with fine stripped microcrystalline structure and with equiaxied very fine microcrystalline structure are found in sequence Under very large deformation, it may be cracked along the adiabatic shearing band With regard to discuss the criterion of adiabatic shearing, the distinction among the adiabatic shearing deformation, the adiabatic shearing fracture and the thermoplastic instability is important 收稿日期: 1986-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 卢维娴 王礼立 陆在庆 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/39 1 Bedford, A.J.; Wingrove, A.J.; Thompson, K.
