【摘要】 本文利用自制的光粘弹性材料,用光弹性法研究了在轴向拉伸荷载作用下带有圆孔的杆件中的粘弹性应力集中系数。文中提供了杆件在荷载作用后6秒内每间隔1秒的等差线照片,叙述了有关实验及计算结果,並讨论了确定粘弹性应力集中系数的实用方法的途径。更多还原

【Abstract】 A photoelastic study for the viscoelastic stress-concentration factors in bars with a round hole under axial tension load, using self-made viscoelastic materials is presented in this paper. The paper presents a series of photos for isochromatic patterns at an interval of one second during six seconds after loading. The details of the experiment and computed results are also given here. And the practical method of determining the viscoelastic-stress concentration factors is discussed in this paper.更多还原
