摘要
本文给出了一个零级次弹性圆柱杆在常速度拉伸时有限变形的解析解,由其解发现在不同拉伸速度下应力-应变曲线的不同,完全是由于惯性力而引起,它使轴向应力几乎是随着拉伸速度比值的平方而增加。
In this paper an analytical solution for finite deformation at the simple extension of a hypoelastic cylindrical bar of grade zero under constant velocity is obtained. It is found that the difference between stress-strain curves at different tensile velocities is only due to the inertial terms in the solution. The axial stress due to inertia increases with the square of ratio of tensile velocities.
