摘要
本文用三种实验方法研究对称型含穿透裂纹平板受弯时的离面位移,比较了现有三种理论结果,验证了柳春图从Rcissner理论导出的表达式的正确性,在此基础上,作者提出了一种修正方法,使含裂纹平板的离面位移表达式与实验吻合更好。
The out-plane displacement near the tip of a through crack in an elastic plates, submitted ts symmetric bending, was studied by three experimental methods. Three theories were compared with experiment and the result obtained by Liu Chuenfu was verified. Based upon this work, an amendment method w as proposed to make the expression of the ont-plane displacement of a cracked plate describe real displacement more exactly.
