The dislocation density distribution function (?) (x) is easily obtained by solving the integral equation with the Chebyshev polynomials. Some stress intensity factors thus calculated for practical cases have been found to agree fairly well with the results obtained by the conventional fracture mechanics. 收稿日期: 1978-02-18      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 龙期威 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I2/118 [1] Bilby, B.
