A hole in a plate loaded by bending induces notch stresses in it's surrounding. This stress amplification depends on the shape of the hole. In the present paper this effect is studied by use of the Finite Element Method systematically. It was found that longer holes induce lower notch stresses than circular holes. Some tendency to find the optimate hole shape with lowest stresses is shown. Following this way the danger of plate failure by cracking may be reduced. The shape of the cross-section of the plate was fixed during this considerations.
受弯曲载荷作用的板中的孔洞会在其周围产生缺口应力。这种应力放大取决于孔洞的形状。在本文中，利用有限元方法对这种效应进行了系统研究。结果发现，长形孔洞产生的缺口应力比圆形孔洞低。文中展示了寻找应力最低的最优孔洞形状的一些趋势。通过这种方式，可能会降低板材因开裂而失效的风险。在这些研究中，板材横截面的形状是固定的。
